Answer:
hope it may.help u
Step-by-step explanation:
Given,
Perimeter of parallelogram =96m
Area of parallelogram =270sq.m
In parallelogram ABCD
AB=CD=18m and AD=BC
As we know perimeter one parallelogram 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×l
⇒l=
30
270
⇒l=9m
