How many square units are in an office that is 13 units by 9 units? 22 117 121 130?
The Correct Answer and Explanation is:
To find the area of a rectangular office, you simply multiply the length by the width. In this case, the length of the office is 13 units and the width is 9 units.
The formula for the area of a rectangle is:Area=length×width\text{Area} = \text{length} \times \text{width}Area=length×width
Substituting the given values:Area=13 units×9 units=117 square units\text{Area} = 13 \, \text{units} \times 9 \, \text{units} = 117 \, \text{square units}Area=13units×9units=117square units
Therefore, the area of the office is 117 square units.
Explanation:
When calculating the area of a rectangle, we are determining the amount of space the rectangle occupies. Each unit represents a small square that fits inside the office. By multiplying the length and width, we count how many of those small squares fit inside the entire office.
For example, if you imagine the office as a grid of small 1×1 squares, you would have 13 rows (because the length is 13) and 9 columns (because the width is 9). To find the total number of squares, you multiply the number of rows by the number of columns:13×9=11713 \times 9 = 11713×9=117
So, there are 117 of these 1×1 squares that fit into the office, and thus the total area is 117 square units.
In conclusion, the correct answer is 117 square units.
