Question
The perimeter of a rectangle is 5555 feet. If the length is 1414 feet, find the width.Step 2 of 3: Without substitution, solve the formula for the unknown variable in terms of the known variables.
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.
We are given P (perimeter) = 5555 feet and L (length) = 1414 feet. We are asked to find W (width).
To solve for W, we first subtract 2L from both sides of the equation:
P - 2L = 2W
Then, we divide both sides of the equation by 2 to solve for W:
W = (P - 2L) / 2
This is the formula for the width of the rectangle in terms of the known variables (P and L).
