To find the area of a rectangle, you can use the formula:
[tex]\[ \text{Area} = \text{length} \times \text{width} \][/tex]
Here, you are given:
- Length = 7 feet
- Width = 3 feet
Step-by-step, the solution is:
1. Identify the length and width given in the problem:
- Length = 7 feet
- Width = 3 feet
2. Multiply the length by the width:
[tex]\[ 7 \, \text{feet} \times 3 \, \text{feet} = 21 \, \text{square feet} \][/tex]
Therefore, the area of the rectangle is [tex]\( 21 \, \text{square feet} \)[/tex] or [tex]\( 21 \, ft^2 \)[/tex].
So, the correct answer is:
C. [tex]\( 21 \, ft^2 \)[/tex]
