6. The area of a shape is the amount of space inside it. The area of the shape is 18cm 2. To find out the area inside the shape we can count the squares.

7. Counting each square can take a long time. Does anyone know a quicker way? The area of the shape is 48cm 2. The rectangle is made of 6 rows of 8 squares. To work out the number of squares we multiply 6 by 8. 8cm 6cm A = l x w

8. YOU TRY length width Area = length x width 7cm 10cm Remember Area = l x w 10 X 7 = 70 Area = 70 cm2

9. What is the Area of the rectangle? length width Area = length x width 3cm 11cm What is the perimeter of the rectangle? Area = 11 x 3 A = 33 Perimeter = 11 +11 + 3 +3 Perimeter = 22 +6 = 28

10. We can find the area without a picture. l = 15 cm, w = 6 cm What is the area? l = Means length, w = means width A = l x w 90 cm square

11. You try! Find the Area of the rectangle l = 5 cm, w = 8 cm l = 9 cm, w = 3 cm Find the Area of the square S = 15 cm S = 4 cm

18. 5cm 6cm 12cm 2cm 3cm 6cm Area = 2 x 6 12cm 2 Area = 5 x 6 30 cm 2 Total area = 12 + 30 = 42 cm 2 Perimeter = 34 cm YOUR TRY

21. There are two parks in Katie’s neighborhood. She thinks that North Park has about the same area as Central Park because their perimeters are about the same. Is she correct? North Park Central Park 90 yd 25 yd 42 yd 75yd Find the perimeter of both park. North Park: P = 90+90+25+25=230 Central Park: P = 42+42+75+75=234 A= l x w A= 90 x 25=1,500 yd 2 A=l x w A=42 x 75 A=3,150 yd 2
