Answer:
Step-by-step explanation:
two parts to this one the box in the middle and then a whole circle.. b/c add the 2 halves on each end to make a whole. :)
box in the middle: 15 * 25 = 375
circle: [tex]\pi[/tex][tex]7.5^{2}[/tex] = 176.7145
add the two parts up
176.7145 + 375 = 551.7145
551.6 looks good, I used an extended version of pi... from my calculator
551.6 [tex]ft^{2}[/tex]
