Question

the sides of a triangle are in the ratio 5:12:13. If the perimeter of the triangle is 60cm, the area of the triangle in cm² is​

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

Now,

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

Apply Heron's Formula of find the area of triangle.

Area = S(S−a)(S−b)(S−c)

Where S= a+b+c/2

S= ½ (25+60+65)=75cm

Area = root (75(75−20)(75−60)(75−65))

=root (75×50×15×10)

=750

Area of triangle is 750cm²

Answer 2
