7. Area

8. Lesson:

9. Since all sides of the square are the same you can “square” your number Since all sides of the square are the same you can “square” your number 4 ft To find the area multiply length and width 4 x 4 Or you can square it 4 2

10. 7 ft 7 2 = 49 49 ft 2 Be sure to include units of measure!! Since it is area you need to square the units.

11. 12 m 4.5 in

12. Now that you can find area- let’s undo it!! Area is 25 ft 2 What is one side???

13. Now that you can find area- let’s undo it!! Area is 25 ft 2 What is one side??? What operation would you use to undo a square- the square root!!!

14. Now that you can find area- let’s undo it!! Area is 25 ft 2 What is one side??? √25 = 5 Therefore one side is 5 ft.

15. Area = 81 sq in Area = 36 sq m

16. Area = 81 sq in Now that you found the side Length is 9 in. What is the perimeter???

17. Area = 81 sq in Now that you found the side Length is 9 in. What is the perimeter??? 9 x 4 = 36 in

18. Try this one Step 1: find the side length Step 2: find the perimeter
