By definition of area of a rectangule, the width of the field is 2/3 mile.
Definition of area
The area is the measure of a space delimited by a contour called the perimeter. In other words, area is the measure of the surface of a figure; that is, the measure of its interior region.
Rectangule
A rectangle is a flat geometric figure with four sides, of which two sides that are opposite parallel to each other have the same length and the remaining two have another length.
Area of a rectangule
The area of a rectangle is calculated from the two different sides, and it is calculated by multiplying the length (L) by the width (W):
Area= L×W
This case
In this case, the length of a rectangular shaped field is 3/4 mile. If the area of the field is 1/2 mile², then the width can be calculated as:
1/2 mile²= 3/4 mile× W
Solving:
1/2 mile²÷ 3/4 mile= W
2/3 mile= W
Finally, the width of the field is 2/3 mile.
