Cathy measured a room to be \(10 \frac{1}{2}\) feet by \(12 \frac{5}{8}\) feet. What is the area of the room?
Answer (2)
We know that are for the rectangle is A=a b, where A i area, a is one side and b is second side. It doesnt matter side we assume a or b because multiplicity is commutative. We can substitute our data to formula A=[tex]10 \frac{1}{2} 12 \frac{5}{8} = \frac{21}{2} \frac{101}{8}= \frac{21 101}{2*8}= \frac{2121}{16}= 132.56[/tex] [feet squared] - its the answer
The area of the room measuring 10 2 1 feet by 12 8 5 feet is approximately 132.56 square feet. This area is calculated by converting the measurements to improper fractions, multiplying them, and then converting to a decimal. Using the formula A = l × w , we find the area equal to 16 2121 square feet or about 132.56 square feet.
