Answer:
<h2>Cameron solution is not reasonable, because it must have 4 decimals points, not three.</h2>Step-by-step explanation:
When calculating the area of the rectangular wall, we have to multiply 16.5ft(8.625ft), if we observe, we have 4 decimals in total. The multiplications results 142.3125. So, Cameron solution is not reasonable, because he only included three decimals points, instead of four.
