Answer:
6 ft
Step-by-step explanation:
The formula for solving area of a rectangle is length × width = area.
We can plug in the numbers we already know:
length × 1/2 = 3.
Multiplication is the opposite operation of division, so you can use division to find the remaining variable:
3 ÷ 1/2 = 6
Check:
6 × 1/2 = 3
