Area of a Rectangle Area = base x height 6 units or Area = width x length Area = 8 x 6 8 units Area = 48 square units Area is measured in square units because we measure in two directions.

Area of a Right Triangle 6 units 8 units To find the area of a triangle we start with the formula for area of a RECTANGLE.

base x height Area = 8 x 6 2 2 Area = Area of a Right Triangle Area of the triangle = 24 square units 6 units 8 units To find the area of a triangle we start with the formula for area of a RECTANGLE. Then we divide by 2.

base x height Area = 8 x 6 2 2 Area = Area of a Right Triangle 6 units 8 units The AREA of the triangle is HALF the AREA of the rectangle.
