Length = 16 meters
Width = 12 meters
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Let
length = x
Width = (x - 4) meters
Perimeter of the rectangular pool = 56 meters
Perimeter of a rectangle = 2(length + width)
56 = 2{x + (x - 4)}
56 = 2(x + x - 4)
56 = 2(2x - 4)
56 = 4x - 8
56 + 8 = 4x
64 = 4x
x = 64/4
x = 16
length = x = 16 meters
Width = (x - 4) meters
= 16 - 4
= 12 meters
