Answer:
54 square units
Explanation:
First, divide the composite figure into common plane shapes as shown below:
Thus, we have two plane shapes:
• A triangle with a base of 10 units and a height of 6 units.
,• A rectangle with a length of 6 units and a height of 4 units.
Therefore:
[tex]\begin{gathered} \text{ Area of the composite figure}=\text{ Area of the triangle+Area of the rectangle} \\ =\frac{1}{2}bh+lh \\ =(\frac{1}{2}\times10\times6)+(6\times4) \\ =30+24 \\ =54\text{ square units} \end{gathered}[/tex]The area of the composite figure is 54 square units.
