Question from Peggy: roll of paper 3ft wide and roll equals 500 sq ft how long would the roll be? |
Hi Peggy,
If you roll out the roll of paper it becomes a long rectangle 3 feet wide. The area of a rectangle is the length times the width and hence for your rectangle
\[\mbox{length }\times 3 = 500.\]
Solve for the length,
Penny
