 Area is the number of square units needed to cover a surface.You can use a formula to find the area of a square, rectangle, right triangle, and a parallelogram. Area is always answered in square units.

 Example 1: Rectangle Find the area of the rectangle using  the formula. To find the area of a rectangle, multiply the length x width Area = length x width The length = 6 ft The width = 2 ft Area = 6 ft x 2 ft The area is 12 square feet.

 Example 2: Square Find the area of the square using  the formula. To find the area of a square, multiply the side x side Area = side x side Area = 3 ft x 3 ft The area is 9 square feet.

 Example 3: Right Triangle Find the area of the right triangle using the formula. Area = 1/2 x base x height A= 1/2 x b x h A= 1/2 x 8m x 5m A= 1/2 x 40 square meters A= 20 square meters The area is 20 square meters.

 Example 4: Parallelogram Find the area of the parallelogram using the formula. Area = base x height A= b x h A= 4 units x 3 units A= 12 square units The area is 12 square units.

 Remember: formulas Rectangle : A = l x w Square: A = s x s Right triangle: A = 1/2 b x h Parallelogram: A= b x h
