Question

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

​

Answer 1

Answer:

Let

the first side = x cm

second side = x+1 cm

third side = x+2 cm

Perimeter of the triangle = 72 cm

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

x + x + 1 + x + 2 = 72 cm

3x+3= 72 cm

3x = 72-3

3x = 69 cm

x = 69/3

x = 23 cm

therefore,

the sides of triangles are 23 cm, 24 cm and 25 cm
