Question

A square has a perimeter given by the expression 16x+32y. Write an expression for the length of one side of the square.

Answer 1

A square has 4 equal sides which make up the perimeter.

Therefore the length of one side = (16x + 32y) / 4  = 4x + 8y Answer

Answer 2

A square has 4 sides with equal length.
The perimeter is the sum of the 4 equal lengths.
The perimeter is also 4 times the length of one side.
Each side is 1/4 of the perimeter.

P = 16x + 32y

s = P/4 = (16x + 32y)/4 = 4x + 8y

Answer: 4x + 8y
