Final answer:
The area of the rectangle with a length of 15 cm and a width of 3/5 cm is 9 cm², and the perimeter is 31.2 cm.
Step-by-step explanation:
To find the area and perimeter of a rectangle, we use the formulas: area = length × width and perimeter = 2 × (length + width). Given the length of the rectangle is 15 cm, and the width is given as a fraction, 3/5, which can be also written as 0.6 cm.
First, we calculate the area:
- Area = length × width
- Area = 15 cm × 0.6 cm
- Area = 9 cm²
Next, we calculate the perimeter:
- Perimeter = 2 × (length + width)
- Perimeter = 2 × (15 cm + 0.6 cm)
- Perimeter = 2 × 15.6 cm
- Perimeter = 31.2 cm
Therefore, the area of the rectangle is 9 cm², and the perimeter is 31.2 cm.
