Question

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

Answer 1

Perimeter of triangle =72 cm

Let the sides of triangle be : n,n+1,n+2

∴ According to Question

$\sf \:(n)+(n+1)+(n+2)=72$

$\sf \longrightarrow 3n+3=72$

$\sf \longrightarrow\: 3n=69$

$\sf \longrightarrow \: n = \cancel \frac{69}{3}$

$\sf\longrightarrow \: n=23$

ㅤ

• n=23
• n+1=23+1=24
• n+2=23+2=25

ㅤ

Side of triangle are (23, 24, 25) cm

Answer 2
