the perimeter of a rectangular swimming pool is 40 ft. the length of the pool is 12 ft. what is the area of the pool
A equal L x W
if the perimeter is 40 and you know that the length is 12...P equals 2(L)plus2(W).Your two lengths would ne 24 so your 2 widths would be 16. (8 plus 8)
12 times 8 is 96 sq ft for the area.
40 multiplyed by 12 equalls area
480 units squared
To find the area of a rectangular swimming pool, we need to know the length and width of the pool. However, in this case, we are only given the length and the perimeter of the pool.
The formula for the perimeter of a rectangle is (2 * length) + (2 * width). Since the perimeter is given as 40 ft, and the length is given as 12 ft, we can substitute these values into the formula to solve for the width.
40 = (2 * 12) + (2 * width)
40 = 24 + (2 * width)
Next, we need to isolate the width variable.
40 - 24 = 2 * width
16 = 2 * width
We can simplify the equation by dividing both sides by 2:
16 ÷ 2 = width
8 = width
Now that we know the width of the pool is 8 ft, we can calculate the area using the formula for the area of a rectangle, which is length multiplied by width.
Area = length * width
Area = 12 ft * 8 ft
Area = 96 square feet
Therefore, the area of the rectangular swimming pool is 96 square feet.
