Perimeter and Area (VCE SSCE General Mathematics): Flashcards

Branch of maths measuring length, area & volume

Total distance around outer edge of a shape

Square units (mm², cm², m², km²)

$A = \frac{1}{2}bh$

$A = \frac{1}{2}(a + b)h$

$A = \sqrt{s(s-a)(s-b)(s-c)}$

$s = \frac{a+b+c}{2}$

Shape made of 2+ basic shapes joined together

$C = 2\pi r$ or $C = \pi d$

$A = \pi r^2$
