Question

What is the perimeter of a rectangle if the length of the short sides are 5", and the other sides are both y?

Answer 1

perimeter of a rectangle = 2L +2W

 if w = 5 and l = y

 then

 perimeter = 2y +2(5) =

Perimeter = 2y+10

Answer 2

5 + 5 + y + y = perimeter
simplified, the answer is 10 + 2y
