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 r^{2} (r = radius, distance from the outline to the centre)

circumference of a circle= pi x d (d = diameter, twice the radius)
