Question

perimeter of a triangle is 28 cm and a incircle is present inside the triangle the radius of the incircle is 4 cm find the area of the triangle

Answer 1

Let the length of the base be x respectively.

Area of triangle = 1/2 ×base ×height

=1/2×x×(4×2)*

=4x sq.cm Ans.

The star(*) resembles that the radius is half of the height of triangle.Therefore,it will be (4×2)
