Question

9. The sides of a triangle are given as a, 2a+3 and 3a-3.If the perimeter is 60cm, find the smallest side of the triangle.

Answer 1

Given the sides of triangle be a,(2a+3),(3a−3)

since perimeter =60 cm

⇒a+(2a+3)+(3a−3)=60

⇒a=10

therefore smallest side of the triangle is =10cm

Answer 2

Answer:

a=10

Step-by-step explanation:

a+(2a+3)+(3a-3)=60

(a+2a+3a)+(3-3)=60

6a=60

a=60/6

a=10

recheck

10+10*2+3+3*10-3=60

10+20+30+3-3=60

30+30=60

60=60

hope this answers is helpfull
