Area, Perimeter, and VolumeCreated by Barbara FugittTexarkana ISD
Perimeter of a RectangleThe perimeter is the distance around a figure.The formulas are: P = 2L + 2W P = 2 (L + W)Measured in single units.15 in.8 in.P = 2(8 in.) + 2(15 in.) P = 2 (8 in. + 15 in.)P = 16in. + 30 in. P = 2 (23 in.)P = 46 in. P = 46 in.
Perimeter of a SquareThe perimeter is the distance around a figure.The formula is: P = 4sMeasured in single units.9 in.P = 4sP = 4(9in.) or 4 x 9 in.P = 36 in.
Perimeter of a TriangleThe perimeter is the distance around a figure.Add up all three sides. P = A + B + CMeasured in single units.5 inches5 inches5 inchesP = A + B + CP = 5 in. + 5 in. + 5 in.P = 15 in.
Area of a RectangleThe number of square units needed to cover the surface of a figure.The formula is: A = L x WArea is measured in square units.14 in.9 in.A = L x WA = 14 in. x 9 in.A = 126 square in.
Area of a SquareThe number of square units needed to cover the surface of a figure.The formula is: A = s² or A = s x sArea is measured in square units.6 in.A = s² A = s x sA = 6 in.² A = 6 in. x 6 in.A = 36 sq. in. A = 36 sq. in.
Area of a TriangleThe number of square units needed to cover the surface of a figure.The formula is: A =½bh or A = bh 2Area is measured in square units.5 in.5 in.5 in.4 in.A =½bh A = ½(5 in. x 4 in.)A = ½ (20 sq. in.)A = 10 sq. in.
VolumeThe volume is the amount of space occupied by a three-dimensional object.The formula is V = L x W x HVolume is measured in cubic units.5 in.2 in.5 in.V = L x W x HV = 5 in. x 2 in. x 5 in.V = 10 sq. in. x 5 in.V = 50 cubic in.
