Question

9. The sides of a triangle are in the
ratio of 5:12: 13 and its perimeter is
150 m. The area of the triangle is:
(2 points)
​

Answer 1

Answer:

Perimeter of triangle =150m (given)

Let the sides of triangle be,a, b and c,

On dividing 150 m in the ratio 5:12:13, we get

a=5xcm

b=12xcm

c=13xcm

we know that, perimeter of a triangle = Sum of all sides =a+b+c

150=5x+12x+13x

150=30x

x=5

Sides are:

a=5x=25cm

b=12x=60cm

c=13x=65cm

Hope this Helps!
