Question

The ratio of two sides of parallelogram is 3 : 5 and its perimeter is 48 cm. Find the sides of the parallelogram

Answer 1

The ratio of two sides of parallelogram is 3 : 5 and its perimeter is 48 cm.
Let length = l and breadth = b (l >b)
Then b : l = 3: 5
=> $b=\frac{3l}{5}$
Perimeter = 2 (l+b) = 48 cm
=> $2(l+\frac{3l}{5})=48$
=> $\frac{8l}{5}=24$
=> l = 15 cm
then b = 9 cm
Then sides are $15$ cm, $9$ cm,$15$cm, $9$ cm.
