### Geometry and Measurement

TermDefinition
Area The amount of surface a figure covers. Two dimensional
Area of a Square Area = side X side A=sXs or Area = length X width A=lw
Area of a Rectangle Area=base X height A=bh or Area = length X width A=lw
Area of a Triangle Area=baseXheight divided by 2 A=bh/2 or Area= 1/2 base X height A=1/2 bh
Area of a Parallelogram Area = base X height A=bh
Area is Measured in_______________units Square units!!!!!!!!!!!!
When finding area of a triangle make sure you are multiplying base X height Not the length of the side unless its a right triangle
Composite Figures Shapes made up of more than one polygon. For example a picture of a house can be a triangle and a rectangle.
If a rectangle has a base of 8in and a height of 4in what is the area? Area=32 inches squared A=8X4
If a triangle has a base of 12ft and a height of 6ft whats the area? A=12X6 divided by 2 A=36ft squared
A parallelogram in the shape of a kite has all sides that measure 4ft and a height of 3ft Area= A=4X3 Area =12 feet squared
Strategy to solve area problems Draw it out!!!!!!!! to check your work
