Answer:
15/7 mi.
Explanation:
1. The length of the rectangular strip of land is 1/3 mi.
2. The area of the rectangle is 5/7 square mile.
3. The formula for the area of a rectangle is length multiplied by width.
4. Let's use the formula and solve for the width:
- Area = Length * Width
- 5/7 square mile = 1/3 mi * Width
- To isolate the width, we divide both sides of the equation by 1/3 mi: (5/7 square mile) / (1/3 mi).
- When dividing fractions, we multiply by the reciprocal of the divisor. So, we can rewrite the division as multiplication: (5/7 square mile) * (3 mi/1).
- Multiply the numerators: (5 * 3) = 15.
- Multiply the denominators: (7 * 1) = 7.
- The fraction expression that can be used to find the width is 15/7 mi.
Therefore, the width of the rectangular strip of land is 15/7 mi.
