The perimeter of a parallelogram is 22c ...

The perimeter of a parallelogram is `22c mdot` If the longer side measures `6. 5c m` what is the measure of the shorter side?

Text Solution

Verified by Experts

Perimeter`=22 cm`
Longest side`=6.5 cm`
Let shorter side`=x`
`2xx(6.5+x)=22`
`13+2x=22`
`2x=22−13=9`
`x=9/2=4.5`
`therefore` Shorter side`=4.5cm`
