2. AREA VS. PERIMETER

3. OBJECTIVE: Today we will learn how to calculate the Area & Perimeter of different size quadrilaterals! COOL!

4. PERIMETER Is the distance around a figure, the “OUTSIDE” + ADD + (Find the sum of all the sides) Imagine a backyard, the Perimeter is the fence that shapes the backyard 30 ft 50 ft P = 30 + 30 + 50 + 50 = 160 ft

5. Is the amount of space (square units) found “INSIDE” the boundary of a 2D shape Measured in “Square Units” (m, in, ft, yd ) × MULTIPLY × (Rectangle or Square = L × W) 2222 8 ft 2 A = L × W 8 x 8 = 64 ft

6. Area: Farmer Hackett wants to make a rectangular pig pen for his pigs. He wants to make it 8 m Long by 13 m Wide. What would be the Area of Farmer Hackett’s pig pen? 13 m 8 m

7. Perimeter: Farmer Hackett is fencing in his pig pen. The dimensions are 8 m long and 13 m wide. What is the Perimeter of his pig pen? 8 m 13 m

8. More Practice: Find the Perimeter & Area of a Basketball Court 94 ft 50 ft P = 288 FT A= 4,700 ft. sq

9. Find the Area & Perimeter of the Wrestling Mat: WRESTLE MANIA 20 Ft

10. Farmer Hackett decided to build a rectangular brick walkway into the pigpen. If the dimensions of the walkway are 7m by 2m, What is the area of the pigpen NOT covered in brick? 8 m 13 m 7 m 2 m A = 90 m sq

11. Farmer Hackett has a plot of land which is a perfect square. 300 m Long and 300m Wide. What is the area of the land? Farmer Hackett decided to diagonally cut the land in half and grow corn on one side, and wheat on the other. What is the area of the corn field? CORN WHEAT 300 m 90,000 m sq. 45,000 m sq. *What does this teach us about triangles??
