Question

the adjacent sides of parallelogram are in ratio of 4:7. the perimeter is 121 cm find the sides of parallelogram

Answer 1

Answer:

ATQ,

4x + 7x + 4x + 7x = 121 cm

22x =121 cm

x = 5.5 cm

Hence, the sides are 22cm, 38.5 cm, 22cm, 38.5 cm

Answer 2

Answer:

Let the sides be 4x, 7x, 4x and 7x respectively.

(because opposite sides are equal.)

So, 4x+4x+7x+7x=121

8x+14x=121

22x=121

x=121/22

x=11/2

Therefore the sides are

4×11/2=22cm.

22cm.

7×11/2=77/2=38.5cm

38.5cm.

respectively.
