Question

the side of a triangle are three consecutive integers perimeter is 120 cm .Find largest siDe​

Answer 1

Step-by-step explanation:

Hiii.

Let first side be x ,

second be x+1 &

third be x+2. (because sides are consecutive)

A.T.Q.

x+x+1+x+2 = 120

3x+3 = 120

3x = 120-3

x = 117÷3

x = 39

Therefore,

First side = 39cm

Second side = 40cm

Third side = 41cm

So the largest side will be 41cm.
