Question

ABCD is a parralelogram such that side=4cm and perimeter of ABCD is 22 m then find length?​

Answer 1

In parallelogram,

We know that opposite sides are equal.

Let, two of the sides are x and y

But it is given that one side is 4cm

Let x = 4cm

So,

Perimeter = x + y + x + y

=> 22 = 2x + 2y

=> 22 = 2(4) + 2y

=> 22 = 8 + 2y

=> 14 = 2y

=> 7 = y

=> y = 7 cm

Hope this helps ✌✌✌
