Answer:
Step-by-step explanation:
Draw your figures the same way as I did, and see if you understand the explanations before writing them down. It's most important to learn from your work :)
One and a half = 1.5
Three and a half = 3.5
1.5 + 3.5 = 5.
First convert to feet
3in=3/12=1/4ft
5.5in=5.5/12ft
1:30
multiply scale by 30
1/4ft times 30=30/4=15/2=7.5ft
5.5/12ft times 30=165/12=13.75ft
multiply them
7.5ft times 13.75ft=103.125 ft^2
closest is option D
