Answer:
17 miles
Explanation:
Let's start by using algebra to solve the problem.
Let's use "L" to represent the length of the land, and "W" to represent the width of the land. We know that the land is 4 1/4 miles wide, which we can write as a mixed number:
W = 4 1/4We also know that the length is 4 times the width:
L = 4WNow we can substitute the first equation into the second equation:
L = 4(4 1/4)
Simplifying the right side of the equation:
L = 4(4) + 4(1/4)
L = 16 + 1L = 17Therefore, the length of the land is 17 miles.
