Question

If the perimeter of Triangle XYZ is 56 cm, what is the perimeter of Triangle ABC?

Answer 1

28 cm

Explanation:

Triangle ABC is obtained by joining the mid points of the sides of triangle XYZ.

So, perimeter of triangle ABC will be equal to half of the perimeter of triangle XYZ.

`P(\triangle ABC) = (1)/(2) * P(\triangle XYZ)`

`P(\triangle ABC) = (1)/(2) * 56`

`P(\triangle ABC) = 28\: cm`
