By use of these formulae, we can easily determine the area of a body.
Area of square = (side)2
Area of rectangle = length x breadth
Area of a triangle = 1/2 (base x height)
Area of trapezoid/ trapezium = 1/2 (distance between parallel sides) x (sum of parallel sides)
Area of circle = πr2 (where, r = radius of circle)
Surface area of a sphere = 4πr2 (where, r = radius of sphere)
Area of parallelogram = base x height
Area of curved surface of cylinder = 2πrl (where, r = radius of cilinder and l = length of cylinder)
Area of ellipse = π x a x b (where, a and b are semi major and semi minor axis of ellipse)
Surface area of a cube = 6(side)2
Total surface area of cone = πr2 + πrl (where, πrl = πr√r2 + h2)
