Question

The sides of a triangle are in the ratio 2:6:7.if perimeter is 30 cm, find the length of each side?

Answer 1

Step-by-step explanation:

Ratio given-

2:6:7

Let each side be 2x, 6x, 7x respectively

According to the question:-

2x+6x+7x=30cm

15x=30cm

Therefore x=2cm

Answers:-

Side 1=2x=2×2=4cm

Side 2=6x=6×2=12cm

Side 3=7x=7×2=14cm.

Answer 2

Given:-

•Side of triangle are in ratio = 2:6:7

•Perimeter of triangle = 30cm

To find:-

• Length of each side = ?

Solution:-

Let the side of triangle be x

Then, the side of triangle will be 2x , 6x, 7x

As we know that,

Perimeter of triangle = sum of all side

30cm = 2x + 6x + 7x

30cm = 15x

x = 2cm

Then,

First side = 2x = 2×2 = 4cm

Second side = 6x = 6×2 = 12cm

Third side = 7x = 7×2 = 14cm

Hence, the side of triangle will be 4cm , 12cm , 14cm
