Mahads Super Fun Page Of Shapes

here are some formulas for finding the areas of shapes:

area of a square= length x length
area of a rectangle= length x width
area of a triangle= 1/2 x base x perpendicular height

area of a parallelogram= base x perpendicular height
area of a trapezium= 1/2(a+b)h
area of a circle= pi x r2 (r = radius, distance from the outline to the centre)
circumference of a circle= pi x d (d = diameter, twice the radius)
