Question

sides of a triangle are in ratio 5:3:3.Perimeter of the triangle is 110cm.find the area of triangle

Answer 1

Let the first, second and third side be 5x,3x and 3x
11x=110cm
x=10cm
First side=50cm
Second side=30cm
Third side=30cm

s=110/2=55
Area of triangle=√s(s-a)(s-b)(s-c)
=√55(55-50)(55-30)(55-30)
