Answer:
The area of the irregular shape is 20 square cm
Step-by-step explanation:
Area of an Irregular Shape
Some shapes do not have regular shapes like squares, circles, triangles, etc. where well-known formulas can be applied to calculate their areas.
We have to calculate the area of the shape provided in the figure. We have divided the shape into three rectangles (see figure below). The total area of the irregular shape is:
A = A1 + A2 + A3
The first rectangle has dimensions 2 cm by 1 cm, thus its area is:
A1 = 1 cm * 2 cm = 2 square cm
The second rectangle has dimensions 2 cm by 3 cm, thus its area is:
A2 = 2 cm * 3 cm = 6 square cm
The third rectangle has dimensions 3 cm by 4 cm, thus its area is:
A3 = 3 cm * 4 cm = 12 square cm
The total area is:
A = 2 square cm + 6 square cm + 12 square cm = 20 square cm
The area of the irregular shape is 20 square cm
