Area Area (A) is the number of nonoverlapping square units of a given size that exactly cover the figure

Area of Rectangle Area = product of its base and height b A= bh h 3 ft 5 ft

Area of a Square Area = product of its base and height A= bh 6 in

Area of a Triangle

Example—finding a side

Perimeter Perimeter (P) of a plane figure is the sum of the side lengths of the figure

Perimeter Formulas Rectangle:l P = 2l + 2w w Square: P = 4s s Triangle: P = a + b + c a b c
