Question

The difference in length between the two adjacent sides of a parallelogram is 5cm.if the perimeter of the parallelogram is 58cm,find measure of all its sides

Answer 1

Step-by-step explanation:

understand it

Assuming the adjacent side are a and b and a is the longer side,

a-b=5cm

The perimeter of the parallelogram is 58cm I. e

2(a+b)=58cm

if a-b=5cm,then a=5cm+b

Remember that 2(a+b)=58cm

2([5cm+b[+b) =58cm

2(5cm+2b)=58cm

10cm+4b=58cm

4b=58cm-10cm

4b=48cm

b=12cm

Recall,a-b=5cm

a-12cm=5cm

a=5cm+12cm

a=17cm
