A blueprint has a scale of 3 feet per \(\frac{\mathrm{1}}{\mathrm{2}}\) inch. If a bathroom is \(1\frac{\mathrm{1}}{\mathrm{2}}\) inches × 2 inches, what are its actual dimensions?
9 feet × 12 feet.
\(4\frac{\mathrm{1}}{\mathrm{2}}\) feet × 6 feet.
6 feet × \(7\frac{\mathrm{1}}{\mathrm{2}}\) feet.
\(7\frac{\mathrm{1}}{\mathrm{2}}\) feet × 9 feet.
Detailed Explanation
If the blueprint shows \(\frac{\mathrm{1}}{\mathrm{2}}\) inch for every 3 feet, then 1 inch represents 6 feet.
The actual dimensions of a room \(1\frac{\mathrm{1}}{\mathrm{2}}\) inches × 2 inches would be (\(1\frac{\mathrm{1}}{\mathrm{2}}\)* 6) by (2 × 6) or 9 feet by 12 feet.
