Question

Find the sides of parallelogram whose sides are in the ratio 4 : 5 and its perimeter is 72 cm​

Answer 1

Answer:

20&16cms

Step-by-step explanation:

let the sides be 4x & 5x

now 2(4x+5x)=72

=2(9x)=72

18x=72

therefore x=4

putting this value we get sides as 4(4)=16cm & 5(4)=20cm

Answer 2

Answer:

The length of the sides of the parallelogram whose perimeter is 72 cm is 16 cm and 20 cm.

Step-by-step explanation:

Let the sides of parallelogram in the ratio be 4x and 5x

Given, Perimeter = 72 cm

Therefore, 72 = 2(L+B) = 2(4x+5x) = 2×9x = 18x

Therefore, value of x = 72/18 = 4

First side = 4x = 4×4 = 16 (answer).

Another side = 5x = 5×4 = 20. (answer).
