To find the width of the rectangular space, we can use the formula for the area of a rectangle, which is:
Area = length * width
Given that the area is 78 square feet and the length is 13 feet, we can solve for the width:
78 = 13 * width
Dividing both sides by 13:
width = 78 / 13
width = 6 feet
So, the width of the rectangular space is 6 feet.
