  1. Area What does it mean?

  2. Area The number of square units needed to cover a space.

  3. Area of Rectangles and Squares = 1 square unit

  4. Area of Rectangles and Squares Is there another way? = 1 square unit

  5. Area of Rectangles Area = 6 sq. units Area = 28 sq. units

  6. Area of Rectangle Formula 4 in l x w = area of a rectangle length x width l x w = 7 in 7 x 4 = 28 sq. in.

  7. Find the Area Use: l x w = area of a rectangle 10 yds 1 yds l x w = Step 1: Write the formula. 10 x 1 = Step 2: Replace the variables. 10 x 1 = 10 Step 3: Multiply. Step 4: Write the answer with the correct units. 10 sq yds

  8. 9 in 3 in Find the Area Use: l x w = area of a rectangle l x w = Step 1: Write the formula. 9 x 3 = Step 2: Replace the variables. 9 x 3 = 27 Step 3: Multiply. Step 4: Write the answer with the correct units. 27 sq in

  9. 4 cm 8 cm Try this one on your own. l x w = Step 1: Write the formula. 8 x 4 = Step 2: Replace the variables. 8 x 4 = 32 Step 3: Multiply. Step 4: Write the answer with the correct units. 32 sq cm

  10. Area of Squares Area = 16 sq. units Area = 4 sq. units

  11. Area of a Square Formula s2= area of a square s2 means s x s side x side 4 in s2 42 =4 x 4 16 sq. in.

  12. Find the Area Use: s2 = area of a square 8 yds s2 = s x s Step 1: Write the formula. 8 x 8 = Step 2: Replace the variables. 64 sq yds Step 3: Multiply and write the correct units in your answer.

  13. 9 cm Find the Area Use: s2 = area of a square s2 = s x s Step 1: Write the formula. 9 x 9 = Step 2: Replace the variables. 81 sq cm Step 3: Multiply and write the correct units in your answer.

  14. 6 mm Try this one on your own. s2 = s x s Step 1: Write the formula. 6 x 6 = Step 2: Replace the variables. 36 sq mm Step 3: Multiply and write the correct units in your answer.

  15. Let’s Review • Area is the number of square units in a space. What is the formula for finding the area of a rectangle? What does area mean? l x w What is the formula for finding the area of a square? s2 = s x s

  16. Now it is your turn.
