Final answer:
To find the perimeter of the rectangle, you multiply the length (18) and width (6) by 2 each and add the results together, giving a perimeter of 48 units.
Step-by-step explanation:
To find the perimeter of a rectangle, you use the formula P = 2l + 2w, where ‘l’ represents the length and ‘w’ represents the width. In this case, the rectangle has a width of 6 and a length of 18. Applying the formula, we calculate the perimeter as follows:
P = 2(18) + 2(6)
P = 36 + 12
P = 48
So, the perimeter of the rectangle is 48 units.
