Answer:
area of sector-The area of a sector of a circle is ½ r² ∅, where r is the radius and ∅ the angle in radians subtended by the arc at the centre of the circle.
area of rectangle-l×b
area of square-side^2
perimeter of square-4×side
perimeter of rectangle-2(length+breadth)
circumference of Circle-2πr
area of Circle-πr^2
circumference of semicircle-πr
area of quadrant- πr^2/4
may be this will help you..............
