Certainly! Let's go through the steps to find the perimeter and area of the rectangle given that the length is 15 inches and the width is 5 inches.
### Finding the Perimeter:
1. Formula for Perimeter of a Rectangle:
The perimeter \(\( P \)\) of a rectangle is calculated using the formula:
\(\[
P = 2 \times (\text{length} + \text{width})
\]\)
2. Substitute the given values:
The length \(\( l = 15 \)\) inches, and the width \(\( w = 5 \)\) inches. Substitute these values into the formula:
\(\[
P = 2 \times (15 + 5)
\]\)
3. Perform the operations inside the parentheses first:
\(\[
15 + 5 = 20
\]\)
4. Multiply the sum by 2:
\(\[
P = 2 \times 20 = 40
\]\)
5. Units:
Since we're dealing with inches, the perimeter will be in inches.
- Perimeter:
\(\[
P = 40 \text{ inches}
\]\)
### Finding the Area:
1. Formula for Area of a Rectangle:
The area \(\( A \)\) of a rectangle is calculated using the formula:
\(\[
A = \text{length} \times \text{width}
\]\)
2. Substitute the given values:
Again, the length \(\( l = 15 \)\) inches, and the width \(\( w = 5 \)\) inches. Substitute these values into the formula:
\(\[
A = 15 \times 5
\]\)
3. Multiply the length by the width:
\(\[
15 \times 5 = 75
\]\)
4. Units:
Since the length and width are in inches, the area will be in square inches.
- Area:
\(\[
A = 75 \text{ square inches}
\]\)
### Summary:
- Perimeter: 40 inches
- Area: 75 square inches
