Question

The longest side of a tringle is three times the short side is 2 shorter than the longest side if perimeter of tringle is at least 61cm.find minimum length of short side

Answer 1

12,30&8 are the sides

Answer 2

Step-by-step explanation:

Let shortest side =a

Then, longest side =3a

Third side =3a−2

Perimeter =a+3a+3a−2=61cm ⇒7a=61+2⇒a=

7

63

=9cm

Hence, shortest side =9cm
