Question

A figure is made up of two triangles and a square. The trianglesand the square have the same base length of 9 feet. Thetriangles have a height of 12.3 feet. What is the total area of thefigure?

Answer 1

`\begin{gathered} \text{Total area= square´s area + triangles´ area} \\ \text{squares area= }(9)\cdot(9) \\ \text{squares area= 81 ft}^2 \\ \text{Triangles area =2}\cdot\text{ (}((12.3)\cdot(9))/(2)\text{)} \\ \text{Triangles area =}110.7ft^2 \\ \text{Total area=81 ft}^2\text{ + }110.7ft^2 \\ \text{Total area=191.7}ft^2 \\ \text{The total area of the figure is 191.7}ft^2 \end{gathered}`
