Question

. The sides of a triangle are in the ratio 5:12:13 and perimeter of the triangle is 120 m. Find the area of the triangle

Answer 1

5x+12x+13x=120

(You will get the value of x, then multiply it with the ratios..you will get the three side of the triangle. Then apply Heron's Formula

Area=√s(s-a)(s-b)(s-c)

s=a+b+c/2
