Answer 2

Hi friend,


Note-:

1/2--half
b--base
h--height
L--length
B--breadth

----------------------------------------------------------------------

Area of trapezium- 1/2*h(sum of parallel sides)

Area of parallelogram-b*h

Area of rhombus- 1/2*d1*d2

Area of triangle- 1/2*b*h

Area of rectangle- L*B

Area of square- (side)^2

Area of circle- pi*r^2

Area of semicircle-1/2*pi*r^2

Area of sector- pi*r^2*(C/360°) [if we know centre angle].
