Answer:
Area of Rectangle = L * W
where,
Area = 500 sq.ft
L = Length
W = Width = 20 feet
Let's solve for the missing Length,
Area of Rectangle = L * W
500 = L * 20
L = 500/20
L = 25 feet
Perimeter of Rectangle is just the sum of all the 4 sides,
so,
Perimeter = L + W + L + W
or we can say it as,
Perimeter = 2L + 2W
Now solve for the Perimeter,
Perimeter = 2L + 2W
Perimeter = 2(25) + 2(20)
Perimeter = 50 + 40
Perimeter = 90 feet
