Question

if the ratio of two sides of a parallelogram is 4:5 and its perimeter is 90 cm ,its sides​

Answer 1

ANSWER:-

The two sides of a parallelogram are in the ratio 4:5. Let the sides be 4x and 5x. So, perimeter of parallelogram = 2 (4x + 5x) = 90 cm. or 2(9x) = 90 or 9x = 45 or x = 5 So, sides are 4x = 4 x 5 = 20 cm and 5x = 5 x 5 =25 cm.

Answer 2

Answer :

length = 20cm , breadth =25cm

Explanation :

Let, s length =4x and breadth = 5x

Perimeter of parallelogram =2(l+b)

90cm = 2(4x+5x)

90cm= 2(9x)

90=18x

90/18= x

5=x

length = 20cm , breadth =25cm
