EXPLANATION:
To find the area of the complete figure we must first do
-Find the area of the triangle using the formula for the area of the triangle; A=bxh/2
-Then find the area of the irregular rectangle using the formula A = b x h
Finally we must add the two areas found, the exercise is as follows:
[tex]\begin{gathered} A1=(\text{Triangle)} \\ A2=(\operatorname{Re}c\tan gle) \\ A1=\frac{6\operatorname{cm}\times12\operatorname{cm}}{2}=\frac{72}{2}=36\operatorname{cm} \\ A2=21cm\times12cm=252\operatorname{cm} \\ \text{Now we must }add\text{ the two areas} \\ AT=36\operatorname{cm}+252\operatorname{cm}=288\operatorname{cm} \\ \text{ANSWER: The correct option is C : }288cm^2 \end{gathered}[/tex]
