Question

Area of circal and area of triangle

Answer 1

Circle are- πr^2
Triangle area- (1/2) *b*h

π - pi
r - radius of a circle
b - base of a triangle
h - height of a triangle

Answer 2

Area of circle =π r 2

the unit is in square cm or m

Area of triangle = $\frac{1}{2} b \ h$

here , b = base and h = height

area is measured in square cm or m

Heron's formula to find area of traingle = $\sqrt{s (s-a) (s-b) (s-c)}$

where s = $\frac{a +b +c }{2}$
