Question

the adjecent side of a parallegram are in the retio 3:4.if the premater of a parallegram is 84cm. find out it sides.​

Answer 1

Answer:

Let the sides of the parallelogram=3x and 4x.

Perimeter=84cm

Since opposite sides of the parallelogram are equal,

2(3x+4x)=84

14x=84

x=14cm

Sides are 42 and 56

Answer 2

Answer :

18, and 24 cm.

Explanation :

Let the sides be 3x and 4x

Perimeter of a rectangle is = 2(l + b)

=> 84cm = 2(3x + 4x)

=> 84cm = 14x

=> x = 84/14

=> x = 6cm

Hence

3x = 3 × 6 = 18cm.

4x = 4 × 24cm.
