Hicham buys a rectangular sheet of plywood that measures 18 square meters. The sheet of plywood is 3 meters long. What is the perimeter of the sheet of plywood?
A. 9 meters
B. 6 meters
C. 18 meters
D. 18 square meters
To find the perimeter of the sheet of plywood, we need to know the width as well as the length. We are given that the area of the plywood is 18 square meters and the length is 3 meters.
First, we can use the formula for the area of a rectangle: area = length x width. Substituting the given values, we have 18 = 3 x width.
To find the width, we divide both sides of the equation by 3:
18 / 3 = width.
This gives us the width of the sheet of plywood, which is 6 meters.
Now that we know both the length and width, we can calculate the perimeter using the formula for rectangle perimeter: perimeter = 2 x (length + width).
Substituting the values, we have perimeter = 2 x (3 + 6) = 2 x 9 = 18 meters.
Therefore, the perimeter of the sheet of plywood is 18 meters.
The correct answer is C. 18 meters.
