Question

The perimeter of the triangle is 110 ft. If the sides of the triangle are 2x, x-3 and 2x +3, find the area.

Answer 1

If a, b, c are the sides of the triangle, then the perimeter of triangle = (a + b + c) units.

● Area of the triangle = √(s(s - a) (s - h) (s - c))

The semi-perimeter of the triangle, s = (a + b + c)/2

● In a triangle if 'b' is the base and h is the height of the triangle then

Area of triangle = 1/2 × base × height
