Answer:
P = 6 + 4w
Step-by-step explanation:
The length of a rectangle is 3 times greater than its width
Therefore the perimeter of a rectangle can be calculated as follows
P= 2L + 2w
P = 2(w + 3) + 2w
P= 2w + 6 + 2w
P= 6 + 4w
Hence the expression which gives the perimeter of the rectangle in terms of its width is P = 6 + 4w
