b x h = A is the formula for the area of a rectangle.
1/2 x b x h = A is the formula for the area of a triangle.
How are the formulas different?

• a rectangle and triangle are the same.
• The triangle answer must be cut in half.
• b means base and h means horse
• The triangle answer needs to be doubled.
