Question

find area of triangle,square,rectangle,circle

Answer 1

Area of circle = πr² //r is the radius π is a constant == 22/7
Area of square = a² // a is the length of a side of square
Area of rectangle = ab // a is width & b is height
Area of triangle = √(s(s-a)(s-b)(s-c)) // a,b,c are 3 sides of triangle and s is ((a+b+c)/2)

Answer 2

Area of triangle can also be found by using below formula

∆ = 1/2.0*bh

Where b is breath of triangle
and h is hight of triangle

You need one segment of breath and distance height as a perpendicular distance between a point and segment line.
