1. Side of original square ---- x cm

perimeter = 4x

side of new square = x+3
New perimeter = .....

translate: "the perimeter of the new
square is 40 more than twice the length of each side of the original square"
---> new perimeter you found above = 2x + 40

solve for x

4. I had assumed you found the new perimeter to be
4(x+3)
= 4x + 12

so 4x + 12 = 2x+40
I had formed that equation for you, no solve it.
