Question

find the perimeter of a triangle if one side is 11 centimetres , another side is one - fourth the perimeter, and the third side is one - fourth the perimeter .
​

Answer 1

Answer:

Let, perimeter of triangle be x

Now, three sides are 11 cm, (x/4) cm and (x/4) cm respectively.

Now, perimeter of triangle = 11+(x/4)+(x/4)

or, x = 11+(x/2)

or, (x/2) = 11

or, x = 22

hence, perimeter of triangle = 22 cm
