Answer :
The perimeter of pool A is equal to 60 feet.
How to calculate the perimeter of a rectangle?
In Mathematics and Geometry, the perimeter of a rectangle can be calculated by using this mathematical equation (formula);
P = 2(L + W)
Where:
- P represent the perimeter of a rectangle.
- W represent the width of a rectangle.
- L represent the length of a rectangle.
From the perimeter of pool B, we have the following:
120 = 2(L + 20)
120 = 2L + 40
2L = 80
Length of pool B = 80/2 = 40 feet.
Length of pool A = width of pool B = 20 feet.
Width of pool A = 1/4 × Length of pool B
Width of pool A = 1/4 × 40
Width of pool A = 10 feet.
perimeter of pool A = 2(20 + 10)
perimeter of pool A = 60 feet.
