Term | Definition |
---|---|
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 |
