Question

the length of a parallelogram is 2.5m longer than its adjacent side. if the perimeter of the parallelogram is 51m, find it's measure of all its sides ​

Answer 1

Answer:11.5m and 14 m

Step-by-step explanation:

let a be the measure of the shorter side. then longer side is a+2.5

perimeter = 51m

2(a+a+2.5)=51

4a+5=51

4a = 46

a = 11.5

so the sides are 11.5m and 14 m
