Question

The sides of a triangle are in the ratio 3:4:5 and its perimeter is 60cm. Find the perimeter of the triangle

whose vertices are the midpoints of the sides of the given triangle. Write the statement of the theorem

applied.​

Answer 1

Answer:

Given:- Sides of triangle are in ratio 3:4:5 and it's perimeter is 60cm.

Let assume the ratio of traingle to be :- x

3x + 4x + 5x = 60cm

12x = 60cm

x = 60/12

x = 5

Then we will put Value of x in the ratio.

3×5=15cm

4×5=20cm

5×5= 25cm

Therefore Sides of traingle are 15cm, 20cm and 25cm.
