Question

the three sides of a triangle are consecutive integers and their perimeter is 72 cm .Find the measures of each side of the triangle ​

Answer 1

To Find :

• measure of sides of triangle

Solution :

• Perimeter of triangle = 72 cm
• Sides of triangle are cosecutive intigers.

Let the sides of triangle be x , x + 1 , x + 2

Perimeter of∆ = sum of all sides

x + (x + 1) + (x + 2) = 72cm

x + x + x + 1 + 2 = 72

3x + 3 = 72

3x = 72 - 3

x = 69/3

x = 23

So,

Sides of triangle are :--

x = 23cm

x + 1 = 23 + 1 = 24cm

x + 2 = 23 + 2 = 25cm
