Step-by-step explanation:
1. To find the area of the irregular figure, we can break it down into smaller shapes and add up their areas.
First, we can split the shape into two rectangles and a triangle:
Rectangle 1: length = 18 cm, width = 12 cm
Area = length x width = 18 cm x 12 cm = 216 cm^2
Rectangle 2: length = 7.5 cm, width = 6 cm
Area = length x width = 7.5 cm x 6 cm = 45 cm^2
Triangle: base = 7 cm, height = 12 cm
Area = 1/2 x base x height = 1/2 x 7 cm x 12 cm = 42 cm^2
Total area = 216 cm^2 + 45 cm^2 + 42 cm^2 = 303 cm^2
2. To find the area of the irregular figure, we can break it down into two rectangles and a trapezoid:
Rectangle 1: length = 36 cm, width = 9 cm
Area = length x width = 36 cm x 9 cm = 324 cm^2
Rectangle 2: length = 32 cm, width = 16 cm
Area = length x width = 32 cm x 16 cm = 512 cm^2
Trapezoid: lower base = 10 cm, upper base = 14 cm, height = 6 m
First, we need to convert the height to centimeters by multiplying by 100:
Height = 6 m x 100 cm/m = 600 cm
Area = 1/2 x (lower base + upper base) x height = 1/2 x (10 cm + 14 cm) x 600 cm = 4200 cm^2
Total area = 324 cm^2 + 512 cm^2 + 4200 cm^2 = 5036 cm^2
3. To find the area of the irregular figure, we can break it down into a rectangle and a triangle:
Rectangle: length = 21 cm, width = 9 cm
Area = length x width = 21 cm x 9 cm = 189 cm^2
Triangle: base = 9 cm, height = 4 cm
Area = 1/2 x base x height = 1/2 x 9 cm x 4 cm = 18 cm^2
Total area = 189 cm^2 + 18 cm^2 = 207 cm^2
