The answer is A because 5 on 2 sides would equal 10 leaving 40 left dividing it by 2 which is 20.

General formula of the perimeter is
p = 2l + 2w

Given from the question
p = 50
l = 5

Asked from the question
w?

Solution
p = 2l + 2w
2w + 2l = p

Input the numbers to the equation above
2w + 2l = p
2w + 2(5) = 50
2w + 10 = 50
2w = 50 - 10
2w = 40
w = 40/2
w = 20

Each of the other sides is 20 inches
