Question

in the given parallelogram ABCD ,BC is greater that AB by 2cm. if its perimeter is 80 cm ,find AB and BC​

Answer 1

Answer:

AB is 19 cm and BC is 21 cm

Step-by-step explanation:

Let AB be x cm, thus, BC is (x + 2) cm.

2(AB + BC) = 80

Thus, 2(x + x + 2) = 80

Thus, 2(2x + 2) = 80

Thus, 2x + 2 = 40

Thus, 2x = 38

Thus, x = 19
