Question
The perimeter of a rectangular folder is 28 inches. It is 8 inches long. How wide is it? inchesSubmit
Solution
The formula for the perimeter of a rectangle is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.
Given that the perimeter P is 28 inches and the length l is 8 inches, we can substitute these values into the formula:
28 = 2*8 + 2w 28 = 16 + 2w
To solve for w, we subtract 16 from both sides of the equation:
28 - 16 = 2w 12 = 2w
Finally, we divide both sides by 2 to solve for w:
w = 12 / 2 w = 6
So, the width of the rectangular folder is 6 inches.
