Question

Find the approximate lateral surface area of the figure shown. Select one: O 288yd²O 328yd²O 840yd²O 240yd²

Answer 1

The lateral surface area will be the addition of the 3 rectangles in the figure so we can calculate each one:

$\begin{gathered} A_1=12.2\cdot7.04=85.888 \\ A_2=12.2\cdot7.04=85.888 \\ A_3=12.2\cdot10=122 \end{gathered}$

Now we add the areas so:

$85.888+85.888+122=293.776$

So we can aproximate the answer to:

$293.7\approx288$

So the answer is A)
