A rectangular swimming pool, with a width of 9 meters and an area of 450 square meters. What is the perimeter of this swimming pool
Your question is not rigorous. The unit of perimeter is meter, not square meter as you said. Area 450 9=50 meters. It is 50 meters lo ng. Perimeter: 50 2+9 2 = 118 metersA rectangular swimming pool is twice as long as it is wide, and its perimeter is 150. The length and width of this rectangular swimming pool are different
If the width is x meters, then the length is 2x meters. Equation 2 (x+2x) =150 can be listed. Solve the equation to get x=25 meters, 2x=50 meters. A: the swimming pool is 50 meters long and 25 meters wideA rectangular swimming pool is 50 meters long and 27 meters wide. The bottom of the pool is paved with square bricks with an area of 9 square decimeters. It needs more
50*27 (9 100) = 15000 pieces
A rectangular swimming pool, 8 meters wide, 17 meters longer than the width. How many square meters does this swimming pool cover
Solution: a rectangular swimming pool, 8 meters wide, 17 meters longer than the width, that is, the length is: 17+8=25 meters, according to the rectangular area: length According to the width formula, the area of the swimming pool is: 8 25=200 (M2); According to normal logic, the area of this pool is the floor area of this pool! ThereforeA rectangular swimming pool is 20 meters long and 10 meters wide. How many square bricks does it need to be paved with 5 square decimeters of square bricks
A rectangular swimming pool, 20 meters long, 10 meters wide, is paved with square bricks of five square decimeters. How many square bricks do you need? First, calculate the area of the swimming pool, using 20 10=200 square meters, the area of square bricks is square decimeters, here we need a unit of conversion, one square meter is equal to 100 square decimetersA rectangular swimming pool is 58 meters long and 30 meters wide. It should be paved at the bottom of the pool with an area of six square meters long
Solution: because 1 meter =10 decimeters, 58 meters =580 decimeters, 30 meters =300 decimeters, so the bottom area of this rectangular swimming pool =580x300 =174000 decimeters, so to pave a rectangular floor tile with an area of 6 square decimeters at the bottom of the pool, you need l74000 6=29000 such floor tilesA rectangular swimming pool, 60 meters long and 30 meters wide, needs to be paved with square bricks with an area of 9 square decimeters at the bottom of the pool
To solve this problem, first calculate the area of the rectangular swimming pool. The formula of the rectangular area is: s=ab, in which a and B are the length and width of the rectangle respectively, and S is the area of the rectangle. Therefore, the area of the rectangular swimming pool =60 30=1800m²。 Each brick is 9m², So 1800 9=200How much does it cost to build an outdoor swimming pool
It depends on what kind of outdoor swimming pool you want to build. At present, there are two kinds of structures for outdoor swimming pools, one is the traditional concrete swimming pool, and the other is the new steel structure detachable swimming pool; Of course, the investment price of X09 outdoor swimming pool is not random. In addition to the calculation of the swimming pool structure, it is also necessary to determine the size of the swimming pool to determine the model and quotation of the water circulation filtration equipment used in the swimming poolA rectangular swimming pool with a circumference of 480 and a width of 90 meters. What is its length
150 meters. The perimeter is equal to twice the sum of length and width, so the sum of length and width of the swimming pool is 240 meters. Because the width is 90 meters, its length is 150 meters. Perimeter of rectangle = (length + width) 2= long 2+ wide 2. The geometric representation is c=2 (a+b). Rectangle, also known as rectangle, is defined as four quadrangles with equal interior angles, namelyThere is a rectangular swimming pool, which is 25 meters long and 5 meters longer than the width. The perimeter of this rectangular swimming pool is
The width of the swimming pool is: 25-5=20 (meters), (1) (25+20) 2=90 (m), (2) 25 20=500 (square meters), a: the perimeter of this rectangular swimming pool is 90 meters, and the area is 500 square meters
A rectangular swimming pool, 50 meters long and 30 meters wide, needs to be paved with square bricks with a side length of 5 decimeters at the bottom of the pool
It needs 6 000 yuan. The answer process is as follows: 50 30=1500 square meters =150000 square decimals 5 5=25 square decimeter 150000 25=6000 yuan a: 6000 yuan is required
