GCSE Maths Revision Made Easy

24th April 2014

Don't forget these formulae 

Today it's all about area. In our series of Maths GCSE revision posts, we're starting with the formula you'll need and when to use them. 

Area of a rectangle; multiply the length by the width (A= L x W)

Area of a triangle; multiply the base by the perpendicular height and divide by two (A= ½ bh)

Area of a parallelogram; multiply the base by the height (A= B x H

Area of a trapezium; add together the parallel sides and multiply by the height. Divide your answer by two. (A = ½ ( a+b) h)

Area of a circle; square the radius and multiply by pi (A=  π r²)
