Question

A figure is made up of two triangles. The triangles have thesame base of 12 inches. One triangle has a height of 7 inchesand one has a height of 13 inches. What is the total area of thefigure?

Answer 1

We need to find the area of each triangle and then do a sum of both

`\begin{gathered} A_1=(12\cdot7)/(2)=(84)/(2)=42\text{ and } \\ A_2=(12\cdot13)/(2)=(156)/(2)=78\text{ } \end{gathered}`

Then the total area of the figure is 120 inches^2

`42+78=120`
