Area (OCR GCSE Maths): Flashcards

Squared units: $m^2$, $cm^2$, $mm^2$

Height at $90°$ (right angle) to the base

$Area = b \times h$

$Area = \frac{b \times h}{2}$

$Area = b \times h$

$Area = \frac{(p+q)}{2} \times h$

Average of two parallel sides $\times$ height

$Area = \frac{1}{2} \times d_1 \times d_2$

$Area = \pi \times r^2$

$r = \frac{d}{2}$ (radius = diameter ÷ 2)

Split into simpler shapes, calculate each, add areas together

Sum of areas of all faces
