### Transcript

• 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
• 15. Tell whether you would use perimeter or area to help you decide how much of the item to buy.1. Tile a kitchen floor - area2. Sod a lawn - area3. Fence in a yard - perimeter4. Tape need to use when painting - perimeter
• 16. Can you use the perimeter and area formulas to find the perimeter and area of rectangle figures?
