# Ch 1.4 Area in the coordinate plane

Step 1: determine the distance of the base and height.
Base: The base of the triangle goes from point
F(-4, -3) to E(4, -3)
The side is horizontal so you can either do:
/-4-4/ = /-8/ = 8
Or count the graph squares along the line.
Height: The height goes from point D(1, 3) straight down to the base at (1,-3)
Again you can do:
/3- -3/ = /6/ = 6
Or count vertically the graph squares along the line.
step 2: input the base and height into the area formula
A=1/2bh= ½*8*6= ½*48= 24
Use the graph below to plot (2,3) (4,3) (3,6). Then determine the area of the shape
