Question

The sides of triangle are x cm , x+3 cm x+5 cm. If the perimeter of the triangle is 29 cm than find the smallest side of a triangle. a)4 b)7 c)6 d)5

Answer 1

Answer:

Let the length of the third side be x cm.The length of the other two sides is 12 cm and 14 cm.Now, the Perimeter of triangle = 36 cm12+14+x=3612+14+x=3626+x=3626+x=36x=36-26=10x=36−26=10Thus, the length of third side is 10 cm.

Answer 2

Answer:

(b)- 7

Step-by-step explanation:

Firstly we will find all the sides,

Perimeter of the triangle = 29cm

Given sides = x, x+3, x+5

                      x+x+3+x+5=29

                      3x+8=29

                      3x=29-8

                      3x=21

                      x=21/3

                      x=7

 So, the sides will be == 7 cm, 10 cm, 12 cm.
