Answer:

178 sq. ft.

Step-by-step explanation:

The total area can be divided into three sub areas viz., T, R₁ and R₂ as shown in the figure.

∴ Total Area = T + R₁ + R₂.

 Area of a triangle = 1/2 (b X h) where b is the base and h is the height of the triangle.

Area of a rectangle = l X b where l is the length and b is breadth of the rectangle.

Now area of T = [tex]$ \frac{1}{2} (6 \times 6) = \frac{1}{2} (36) = 18 \hspace{2mm} sq. ft. $[/tex]

Now area of the first rectangle R₁ = [tex]$ 6 \times 8 = 48 \hspace{2mm} sq. ft. $[/tex].

Area of the second rectangle R₂ = [tex]$ 8 \times 14 = 112 \hspace{2mm} sq. ft. $[/tex]

∴ Total Area = 18 + 48 + 112 = 178 sq. ft.
