Beyond the Answer

To find the dimensions of the painting, we can set up the equations based on the information given. Let the width be \( x \) inches. Since the painting is 5.65 inches taller than it is wide, the length would be \( x + 5.65 \) inches. The perimeter of a rectangle is given by the formula \( P = 2(\text{width} + \text{length}) \). We know the perimeter is 103.59 inches, so we can write: \[ 2(x + (x + 5.65)) = 103.59 \] Simplifying, we get: \[ 2(2x + 5.65) = 103.59 \\ 4x + 11.30 = 103.59 \\ 4x = 103.59 - 11.30 \\ 4x = 92.29 \\ x = \frac{92.29}{4} \\ x = 23.07 \text{ inches (width)} \] Now, for the length: \[ \text{Length} = x + 5.65 = 23.07 + 5.65 = 28.72 \text{ inches} \] So the dimensions of the painting are: Width: **23.07 inches** Length: **28.72 inches**
