Question

the ratio of adjacent side of a parallelogram is 2:3. Find the length of each side if its perimeter is 80 cm​

Answer 1

answer =16,24,16,24

Step-by-step explanation:

In //gm opposite sides are equal

perimeter =sum of all side

80=2x+3x+2x+3x

80=10x

x=8

length of each side = 2x8=16,3x8=24 ,vice versa

Answer 2

Following are the steps for getting the answer:

Given:

the ratio of adjacent side of a parallelogram is 2:3

Perimeter =80cm

To find:

the length of each side

Solution:

given that,

the ratio of adjacent side of a parallelogram is 2:3

perimeter =80cm

Let, the adjacent  side will be 2x , 3x

we know that,

the opposite side of parallelogram is equal.

so,

the side will 2x,3x,2x and 3x

we also know that,

perimeter =sum of all side

so,

80cm=2x+3x+2x+3x

80cm=10x

80/10=x

x=8cm

2x=2×8=16

3x=3×8=24

hence, the length of each side is 16, 24 ,16 and 24.
