The areas and perimeters of the shapes are:
- Rectangle 1: A = 96 cm^2 and P = 40 cm
- Rectangle 2: A =576 in^2 and P = 86 in
- Rectangle 3: A = 144 ft^2 and P = 60 ft
- Rectangle 4: A = 64 yd^2 and P = 40 yd
- Rectangle 5: A = 280 mm^2 and P = 76 mm
- Rectangle 6: A = 256 m^2 and P = 64 mm
What are areas?
The area of a shape is the amount of space on the shape
What are perimeters?
The perimeter of a shape is the sum of the side lengths of the shape
How to determine the areas and the perimeters?
Area is calculated as:
A = LW
Perimeter is calculated as:
P = 2(L+W)
When the length and the width are factored by 2, the area and the perimeter become
A = 4LW
P = 4(L+W)
Using the above formulas, we have:
Rectangle 1
A = 4LW = 4 * 4 * 6 = 96 cm^2
P = 4(L+W) = 4 * (4 + 6) = 40 cm
Rectangle 2
A = 4LW = 4 * 12 * 12 = 576 in^2
P = 4(L+W) = 4 * (12 + 12) = 86 in
Rectangle 3
A = 4LW = 4 * 3 * 12 = 144 ft^2
P = 4(L+W) = 4 * (3 + 12) = 60 ft
Rectangle 4
A = 4LW = 4 * 2 * 8 = 64 yd^2
P = 4(L+W) = 4 * (2 + 8) = 40 yd
Rectangle 5
A = 4LW = 4 * 5 * 14 = 280 mm^2
P = 4(L+W) = 4 * (5 + 14) = 76 mm
Rectangle 6
A = 4LW = 4 * 8 * 8 = 256 m^2
P = 4(L+W) = 4 * (8 + 8) = 64 mm
