Find the answer of the question with full explanation. (for class 7)
​

Answer 1

ANSWER:

Solution

DE=4cm

BF=8cm

AD=6cm

Area of parallelogram =AD×BF

=6×8=48cm

Now,

Area of parallelogram =AB×DE

∴AB×4=48

⇒AB=

4/48

=12cm

Therefore,

Perimeter of parallelogram =2(AB+AD)

=2×(12+6)

=2×18=36cm
