Perimeter, Area, and Volume (HSC SSCE Mathematics Standard): Flashcards

Fast, efficient land measurement without site visits

Total distance around boundary of a shape

Real distance = Photo measurement × Scale factor

Surface size of a shape in square units (e.g., $m^2$)

Shapes made from multiple simple shapes combined

$V = A \times h$ (area × height/depth)

$A \approx \frac{w}{2}(d_f + d_l)$

Estimating area of irregular shapes with parallel sides

Gives approximation, not exact answer
