Question

two adjacent sides of parellegram are in the ratio of 2:3 and it's perimeter is 70 cm find the sides of parellegram​

Answer 1

Answer:

14cm,21cm,14cm,21cm

Step-by-step explanation:

RATIO=2:3

SO THEN 2x+3x=5x

PERIMETER FORMULA FOR PARALLELOGRAM:2(BREADTH+LENGTH)

TOTAL PERIMETER=70CM

2(2x+3x)=70cm

2(5x)=70cm

5x=70/2=35cm

x=35/5=7cm

x=7cm

so then one side=2x=2*7=14cm

other side=3x=3*7=21cm

then 14cm+21cm+14cm+21cm=70cm

Answer 2

Step-by-step explanation:

1 . Two adjacent sides of parallelogram are in

ratio of 2:3

2 . Let the side be 'X'

2x+3x+2x+3x. (parallelogram has 4 sides)

3 . 10x = 70 cm

(where perimeter of parallelogram is 70cm)

4 . X=7cm

Sides of parallelogram is 2×7, 2×7 ,3×7, 3× 7...

14 cm,14cm,21cm,21cm....
