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
