Question

One side of a paralellogram is 3/4 times its adjacent side,if the peeimetre of the paralellogram is 70cm Find the sidecof the paralellogram.​

Answer 1

Since opposite sides of a parallelogram are equal and parallel,

Let one side be x,

then adjacent side= 3/4x

Perimeter of //gm = 70

$x + \frac{3}{4} x + x + \frac{3}{4} x = 70 \\ \\ \frac{4x + 3x + 4x + 3x}{4} = 70 \\ \\ 14x = 70 \times 4 \\ \\ 14x = 280 \\ \\ x = \frac{280}{4} \\ \\ x = 20$

Hence, the sides of the parallelogram are

20 cm, 15 cm, 20 cm & 15 cm.
