Answer:
- Length = 14.7 inches.
- Width = 4.90 inches
Explanation:
It's given that,
The length of a rectangle is three times its width.
Let width of the rectangle be x and Length of the rectangle be 3x
Perimeter of yhe rectangle is 72 inches.
Area of rectangle is calculated by,
area = length × width
3x × x = 72
3x² = 72
x² = 72/3
x² = 24
x
4.90
Hence,
Width of rectangle = 4.90 inch
Length of rectangle = 3x
3 × 4.90
14.7 inches.
Hence, Length of the rectangle is 14.7 inch and width is 4.90 inch.
