Question

the perimeter of parallelogram is 80 metres if the longer side is 10 M greater than the shorter side find the length of the sides of the parallelogram

Answer 1

let shorter side of parallelogram is x
so , longer side is x +10

opposite sides of parallelogram are congruent
therefore , others two sides are also x and x+10

now , perimeter is sum of all four sides

therefore , x+x+x+10+x+10 = 80
4x + 20 =80
4x = 60
x = 15

shorter side is 15
longer side is 15 +10= 25
