Question

12. The sides of a triangle are given by x, 2x + 2 and 3x - 2. If its perimeter is 30 cm, then
find the smallest side of the tringle​

Answer 1

Answer:

x is the smallest side

Explanation:

x = 5

Answer 2

Answer:

ans is 5

Explanation:

we know that perimeter of triangle =30cm

x + (2x+2)+ (3x-2 )=30

6x =30

x= 30/6

x=5 cm

thus

first side=x=5cm

second side =2x+2= 2×5+2

=10+2

=12cm

and third side = 3x-2

= 3×5-2

= 15-2

=13cm

hence smallest side =5cm
