Question

5) Find the area of the composite figure. 13.1 ft 15.0 ft 7.2 ft А triangle ft2 А parallelogram - ft² А figure ft2

Answer 1

Area of figure = Area of triangule + area of paralelogram

Area of triangule (At):

`A_t=(b\cdot h)/(2),\text{ b = base and h = height}`
`\begin{gathered} A_t=(7.2\cdot3.1)/(2) \\ A_t=(22.32)/(2)=11.16ft^2 \end{gathered}`

Area of paralelogram (Ap):

`\begin{gathered} A_p=b\cdot h \\ A_p=7.2\cdot5 \\ A_p=36ft^2 \end{gathered}`

Area figure = At + Ap = 11.16+36

Area figure = 47.16 ft²
