USING FORMULAS IN GEOMETRY Geometry CP1 (Holt 1-5)K. Santos
Area Area (A) is the number of nonoverlapping square units of a given size that exactly cover the figure A = 36 square units A = 18 square units A = 7 square units A = ????? 14 ????
Area of Rectangle
Area of a Square
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 P = 24 P= 18 P = 16 P= ?
Perimeter Formulas Rectangle:l P = 2l + 2w w Square: P = 4s s Triangle: P = a + b + c a b c
