The figure is composed by 2 rectangles of height: 2 m and width: 1 m, and 1 rectangle of height: 4m and width: 5 m.
The area of a rectangle is computed as follows:
A = width*height
The area of the smaller rectangles are:
A1 = 2*1 = 2 square meters
The area of the bigger rectangle is:
A2 = 5*4 = 20 square meters
Then, the area of the composite figure is:
2A1 + A2 = 2*2 + 20 = 24 square meters
