Question

Perimeter of a parallelogram shaped land is 96m. If one of the sides of this parallelogram is 18m, find the length of the other side.

Answer 1

Perimeter of parallelogram =96cm

Area of parallelogram =270cm

2

In parallelogram ABCD:

AB=CD=18m and

AD=BC

As we know perimeter given parallelogram is:

ABCD=AB+BC+CD+AD

⟹96=18+AD+18+AD

96=36+2AD

AD=BC= 2

60 =30m

Now, area of parallelogram ABCD,

270=AB×DE

DE= 18,270

DE=15m

∴m=15 m

Also, area of parallelogram ABCD,

270=30×I=9m

30

270
