Converting Square Units
Jada has a rectangular board that is 60 inches long and 48 inches wide.
- How long is the board measured in feet? How wide is the board measured in feet?
- Find the area of the board in square feet.
- Jada said,
To convert inches to feet, I should divide by 12.
What went wrong with Jada's reasoning? Explain.
The board has an area of 48 in $ \times $ 60 in = 2,880 in 2 .
If I divide the area by 12, I can find out the area in square feet.
So the area of the board is 2,880 $ \div $ 12 = 240 ft 2 .
