Students will learn how to use the perimeter and area formulas to find the perimeter and area of rectangle figures. The perimeter is the distance around the figure and is calculated by 2 times the length plus 2 times the width. The area is the amount of surface the figure covers and is calculated by length times width. Examples are provided of calculating the perimeter and area of rectangles with given dimensions in meters, feet, and other units.

1. Learning Target:Students will learn how to use the perimeter and area formulas to find the perimeter and area of rectangle figures.

2. What is the difference between finding the perimeter of a figure and the area of a figure?

3. What is the difference between finding the perimeter of a figure and the area of a figure?

4. Perimeter: the distance around the figure.Formula for a Rectangle: Perimeter = 2 times the length plus 2 times the widthp = 2L + 2w(Don’t forget PEMDAS.)Label: feet, meters, inches, etc.

5. Area: the amount of surface the figure covers.Formula for a Rectangle: Area = length times widthA = LwLabel: square feet (ft2), etc.

6. Find the perimeter and area of the rectangle with the given dimensions.Length = 9 m, width = 5 mLength = 50 ft, width = 22 ft

7. Find the perimeter and area of the rectangle with the given dimensions.Length = 9 m, width = 5 mp = 28 m, A = 45 m2Length = 50 ft, width = 22 ftp = 144 ft, A = 1,100 ft2

8. Use the given information to find the missing length.Area of a rectangle = 91 in2 , width = 7 in, length = ?Perimeter of square = 132 cm, side length = ?

9. Use the given information to find the missing length.Area of a rectangle = 91 in2 , width = 7 in, length = 13 inPerimeter of square = 132 cm, side length = 33 cm

10. How would be finding the perimeter and area of a square be different then a rectangle?

11. Formula for a Square:Perimeter = 4 times the side lengthP = 4sArea = (side lengths)2A = s2

12. Find the perimeter and area of a softball diamond which is 60 ft by 60 ft.

13. Find the perimeter and area of a softball diamond which is 60 ft by 60 ft.P = 240 ftA = 3,600 ft2

14. Tell whether you would use perimeter or area to help you decide how much of the item to buy.1. Tile a kitchen floor2. Sod a lawn3. Fence in a yard4. Tape need to use when painting
