Plz answer me fast.....

Answer 1

Hey here is your answer

● Ratio of sides of parallelogram = 3:4
Let it be 3x and 4x

●Perimeter of a parallelogram = 2 ( a + b )

● Perimeter = 70 cm

Put the values and form an equation
● 70 = 2 ( 3x + 4x )
● 70 = 2 ( 7x )
● 70 = 14x
● 70 / 14 = x
● 5 = x

Therefore , value of x is 5

Now put the value of x and multiply,

Sides of parallelogram =
☆ 3x = ( 3 × 5 ) = 15 cm
☆ 4x = ( 4 × 5 ) = 20 cm
