Hi, 

Am asssuming the lengths of the sides are represented by:

2x+3,4x+1 and x+7

Perimeter(sum of the lengths of the sides) is 25in. find the length of each side

2x+3 + 4x+1 + x+7 = 25in

solving for x

7x + 11 = 25in

7x = 14in

x = 2in

Length of the sides are:

4+3 = 7in

8+1 = 9in

2 + 7 = 9in

checking our answer

7in + 9in + 9in = 25in
