Question

The sides of traingle are in the ratio 5:12:13 and its perimeter in 150m find the area of traingle.​

Answer 1

Consider the sides of the triangle as 5x, 12x and 13x

It is given that perimeter of the triangle = 150m We can write it as 5x + 12x + 13x = 150m On further calculation 30x = 150

So we get x = 15/30

By division x = 5m

By substituting the value of x we get 5x = 5 (5) = 25m 12x = 12 (5) = 60m 13x = 13 (5) = 65m

Consider a = 25m, b = 60m and c = 65m So we get By multiplication Area = 750 sq. m

Therefore, the area of the triangle is 750 sq.
