Let the length of the rectangle be \( L \) inches. According to the problem, the width \( W \) can be expressed as: \[ W = \frac{1}{4}L + 1 \] The formula for the perimeter \( P \) of a rectangle is given by: \[ P = 2L + 2W \] Given that the perimeter is 62 inches, we can set up the equation: \[ 2L + 2W = 62 \] Substituting the expression for \( W \) into the perimeter equation: \[ 2L + 2\left( \frac{1}{4}L + 1 \right) = 62 \] Simplifying this, we get: \[ 2L + \frac{1}{2}L + 2 = 62 \] Combining like terms results in: \[ \frac{5}{2}L + 2 = 62 \] Subtract 2 from both sides: \[ \frac{5}{2}L = 60 \] Now, multiply both sides by \(\frac{2}{5}\) to solve for \( L \): \[ L = 24 \text{ inches} \] Next, we can find the width: \[ W = \frac{1}{4}(24) + 1 = 6 + 1 = 7 \text{ inches} \] So, the length of the rectangle is 24 inches and the width is 7 inches.
