Question

Two adjacent angle of a parallelogram are 4 cm and 7 cm.Find its perimeter .

Answer 1

I understood that they are sides. 

We know that, length of the opposite sides of a parallelogram is equal. 

So other two adjacent sides are also of length 4 cm and 7 cm. 

So the perimeter = 4 + 7 + 4 + 7 = 22 cm

Answer 2

You should correct you question.There should be side instead of angle.We know that opposite sides are equal so perimeter=4+4+7+7=22 cm
