There are a total of 117 square units in an office with the dimensions 13 by 9. The square footage of an office is its measure of usable space.
The area of a figure can be calculated by multiplying its length by its breadth. The dimensions of an office are 13 units in length and 9 units in width. The area is 117 square units (or 139 square units). Since area is calculated by multiplying two separate length or width measurements by the same unit, it is typically expressed in square units. If the units in the office are feet, the space is 117 square feet.
