Front

How do you calculate the area of a rectangle on the coordinate plane?

Back

The area of a rectangle is calculated by multiplying its length by its width: Area = Length × Width.

Front

What is the formula for the area of a triangle given its base and height?

Back

The area of a triangle is given by: Area = (1/2) × Base × Height.
