Knowledge

Area (A) is measured in square units, perimeter (P) is measured in units, and circumference (C) is measured in units.

Square

P = 4a

A = a2

Rectangle

P = 2a+2b

A = ab

Parallelogram

P = 2a+2b

A = bh

Trapezoid

P = a+b+c+d

A = 12h(a+b)

Triangle

P = a+b+c

A = 12bh

Circle

C = 2πr

A = πr2
