Question

Exercise 9.2
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:

23cm,24cm and 25cm

Step-by-step explanation:

let the measures of the sides of the triangle be x,x+1 and x+2 because it is consecutive number.

ATQ ( according to the question )

perimeter = 72 cm

so measure of the sides of the triangle are,

x+x+1+x+2= 72

3x+3 = 72

3x= 72-3= 69

x = 69/3= 23

so the measures of the sides are ,

x = 23cm

x+1 = 23+1 = 24cm

x+2 = 23+2 = 25cm

so the measure of the sides of the triangle are 23cm,24cm and 25cm
