Question

ratio of two sides of parallelogram is 2:5 and its peemeter is 70 cm find its side​

Answer 1

Step-by-step explanation:

let the ratio be 2x and 5x

2x+5x=70

7x=70x=10

1side =2×10=20m

2 side=5×10=50m

Answer 2

Answer:

Its sides are 10&25

Step-by-step explanation:

Ratio = 2:5

Perimeter of parallelogram = 70cm

Perimeter of parallelogram for 2 sides = 70/2

                                                                = 35

Perimeter of ratio = 35

2:5 = 35

2x+5x = 35

7x = 35

x = 35/7

x = 5

1st side = 2x

             = 2*5 = 10

2nd side = 5x

               = 5*5 = 25
