A furniture maker is designing a new table. The tabletop will be a rectangle with a length of 6 feet and a width of 4 feet. What is the area of the tabletop?
- A20 square feet
- B28 square feet
- C24 square feet
- D10 square feet
Show answer & explanationAnswer & explanation
Correct answer: C. 24 square feet
To find the area of a rectangle, multiply its length by its width. For a 6-foot by 4-foot tabletop, the area is 6 * 4 = 24 square feet.
Why the other options are wrong
- A. This is the perimeter divided by two, not the area.
- B. This is the perimeter, not the area.
- D. This is the sum of length and width, not area.
Area of a Rectangle
The area of a rectangle is the measure of the two-dimensional space it occupies, calculated by multiplying its length and width.
- Units for area are always square units (e.g., square feet, square meters).
- Area is used to calculate surface coverage.
- Formula: Area = Length × Width.
Memory trick: Rectangles love 'L' and 'W' for their space.
