Find the total area of the two rectangles:
1. L = 3cm W = 4cm
2. L= 4cm W= 4cm
Hint: To find the total area you must find the area of each and then add them together.
1. A = 12cm²
2. A = 16cm²
Total Area ---> 12 + 16 = 28cm2
Find the total perimeter of these two figures:
1. Rectangle: L=2m W=5m
2. Rectangle: L=3m W=1m
Hint: To find the total perimeter you must find the perimeter of each and then add them together.
1. P = 14m
2. P = 8m
Total Perimeter --->14+8 = 22m
The perimeter is 20mm.
The length is 4mm
What is the width?
The width is 5mm

4 cm
Area = 99 m2
length = 11 m
What is the width?
9 m
Find the total area of these two figures:
1. Square: Sides = 2m
2. Rectangle: L = 2m W= 4m
Hint: To find the total area you must find the area of each and then add them together.
1. A = 4m²
2. A = 8m²
Total Area ---> 4 + 8 = 12m2
Find the total perimeter of these two figures:
1. Rectangle: L = 5cm W = 6cm
2. Square: 9cm
Hint: To find the total perimeter you must find the perimeter of each and then add them together.
