Question

The measure of 2 adjacent side of a parallelogram are in ratio 17:7 if second side measure 3.5 cm find the perimeter of the parallelogram

Answer 1

Let the sides be 17x and 7x

7x=3.5

x=0.5

17x=17×0.5

=8.5cm

perimeter =2 (3.5+8.5)

=24 cm

Answer 2

Let the sides of paralellogram be 17a and 7a

According to question
Second side=3.5 cm
7a = 3.5
a= 0.5

First side = 17*0.5
= 8.5

Perimeter of paralellogram =2(8.5+3.5)
=2*12
= 24 cm


Hope this is correct and will help you
