Yes its true, these formulae are given inside the front cover of the exam, but i
guarantee that if you learn them beforehand, you'll be totally incapable of using
them in the exam. YOU MUST LEARN THESE FORMULAE.
Rectangle Area of rectangle = length X width. A=lXw
Triangle Area of Triangle = ½ X base x vertical height. A = ½ x b x hv
"Note that height must always be the vertical height, not the sloping height."
Parallelogram Areas of Parallelogram = base X vertical height A = b x hv
Trapezium Area of Trapezium average of parallel sides x distance between them.
A = ½ X (a+b) x h
Circle DONT MUDDLE UP THESE TWO CIRCLE FORMULAE! e.g. If the radius is
4cm, then A= 3.14x
Area of circle = x (radius)² A = x r² (4x4) = 50.24cm²
Circumference = x Diameter C=xD
= 3.14 (approx)
Di Circumference =
et distance round the
outside of the circle…read more
