Answer:

The length of each side of the original square was 15 inches

Step-by-step explanation:

Let

x------> the length side of the original square

we know that

The perimeter of a square is equal to

P=4b

where

b is the length side of the square

In this problem

b=(x+2.5)\ in

P=70\ in

substitute

70=4(x+2.5)

solve for x

70=4x+10

4x=70-10

x=60/4=15\ in

Let x be the original side length of the square

P=2(l+w) 
70=2((2.5+x)+(2.5+x))
70=2(5+2x) 
70/2 = 5+2x 
35-5=2x
30=2x
15=x 

Therefore, the original length of the square was 15" 

Hope I helped :)
