Question

The ratio of two sides of a parallelogram is 4: 3. If
its perimeter is 56 cm find the length of the side.
(a) 16 cm, 9 cm (b) 16 cm, 12 cm
(c) 15 cm, 10 cm (d) 12 cm, 8 cm​

Answer 1

Step-by-step explanation:

Let common ratio be x

Therefore, the sides of the parallelogram are 4x and 3x.

Perimeter = 2(l+b)

Given,

2(4x+3x) = 56

7x = 56/2

x = 28/7 = 4

Therefore the sides are 4x = 4 × 4 = 16 and 3x = 3 × 4 = 12

Hence, the answer is b.
