Question

Cathy measured a room to be 10 1/2 feet by 12 5/8 feet. What is the area of the room

Answer 1

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=
`10 (1)/(2) *12 (5)/(8) = (21)/(2)* (101)/(8)= (21*101)/(2*8)= (2121)/(16)= 132.56` [feet squared] - its the answer
