Measurement - Perimeter and Area
Work out the perimeter and area using the dimensions given in the table below. Follow the example given by your teacher.
Dimensions | Perimeter | Area |
Example: L = 9 cm W = 8cm | Perimeter =( L + W) x 2 = (9 cm + 8 cm) x 2 = 17 cm + 2 = 34 cm | Area = L x W = 9 cm x 8 cm = 72 sq cm |
L = 12 cm
W = 9 cm | L + W x 2 = 12 cm + 8 cm) x 2 = 50 cm + 2 = 100 cm | L x W = 12 cm x 8 cm = 96 sq cm |
L = 9 cm
W = 6 cm | L + W x 2 = 9 cm + 6 cm) x 2 = 54 cm + 2 = 108 cm | L x W = 9 cm x 6 cm = 54 sq cm |
L = 15 cm
W = 12 cm | L + W x 2 = 15 cm + 12 cm) x 2 = 180 cm + 2 = 360 cm | L x W = 15 cm x 12 cm = 180 sq cm |
L = 20 cm
W = 7 cm | L + W x 2 = 20 cm + 7 cm) x 2 = 54 cm + 2 = 108 cm | L x W = 20 cm x 7 cm = 140 sq cm |
L = 16 cm
W = 8 cm | L + W x 2 = 16 cm + 8 cm) x 2 = 48 cm + 2 = 96 cm | L x W = 16 cm x 8 cm = 120 sq cm |
