Answer:
168 [tex]cm^{2}[/tex]
Step-by-step explanation:
Consider the picture, break it into a rectangle with a triangle on top. Use the following equation to find the total area of the figure.
[tex]A_{total}[/tex] = [tex]A_{rectangle} + A_{triangle}[/tex]
= length×width + [tex]\frac{1}{2} bh[/tex]
= (12cm)(10cm) + [tex]\frac{1}{2}(12cm)(8cm)[/tex]
= 120[tex]cm^{2}[/tex] + 48[tex]cm^{2}[/tex]
= 168[tex]cm^{2}[/tex]
