I will set up your definitions
let each side of the square be x
then each side of the triangle is x-5
"the sum of the perimeters of the two figures is 251 cm"
translate this into your equation, then solve for x
Replace you x value in the definitions.

is the answer is x = 128

not very likely!
that would make the perimeter of the square alone equal to 512
wouldn't your equation have been
4x + 3(x-5) = 251 ??
I get x = 38
(which meets all the conditions)
