A rectangular parking lot has an area of 7/8 of a square kilometer. The length is 1/4 kilometer. What is the width, in kilometer, of the parking lot?
To find the width of the rectangular parking lot, we can use the formula for the area of a rectangle:
Area = Length x Width
Given that the area of the parking lot is 7/8 of a square kilometer and the length is 1/4 kilometer, we can set up the equation:
7/8 = 1/4 x Width
To solve for the width, we need to isolate the variable "Width". We can start by multiplying both sides of the equation by the reciprocal of 1/4, which is 4/1 or simply 4:
7/8 x 4 = 1/4 x 4 x Width
28/8 = Width
Simplifying further, we divide both the numerator and denominator of 28/8 by 4:
7/2 = Width
Therefore, the width of the parking lot is 7/2 kilometers or 3.5 kilometers.
