Explanation:
The area of a rectangle is 228 square feet and the length of the rectangle is 12 feet, the width is unknown.
Area of rectangle= 228 square feet
Length= 12 feet
Width= Unknown
Let width be represented by w
Area of a rectangle= length×width
228ft^2 = 12ft × w
w = 228/12
w = 19
This means that the width of the rectangle is 19 feet
