First, we divide the figure into four parts as shown in the figure below:
The first part is a major rectangle with dimensions 15x7 m, the second part is a square with side 2 m, the third part is a minor rectangle with dimensions 7x2 m and the fourth part is a semicircle with radius 3 m. The total area of the figure is the sum of the area of each part.
The area of the major rectangle is given by:
A1 = 15*7 = 105 m²
The area of the square is given by:
A2 = 2*2 = 4 m²
The area of the minor triangle is given by:
A3 = 7*2 = 14 m²
The area of the semicircle is given by:
A4 = 3.14*3² = 28.26 m²
Therefore, the total area is given by:
A1 + A2 + A3 + A4 = 105 + 4 + 14 + 28.26 = 151.26 m²
