Question

3. The ratio of the adjacent sides of a parallelogram is as 2 : 3, and its perimeter is
40 cm. Find the sides of the parallelogram.​

Answer 1

Answer:

The ratio of adjacent sides of a parallelogram is 2:3

Let the lengths of the adjacet side be 2 and 3x respectively.

Also,perimeter=50cm

$2(2x + 3x) = 50cm$

$10x = 50cm$

$x = \frac{50}{10} = 5cm$

Thus, the adjacent sides of parallelogram are 10cm and 15cm

Hence area =

$15 \times 10 = 150cm{}^{2}$
