Georgia [21]
The actual block is 1800 feet long and 1260 feet wide. We know that 1 foot is equivalent to 12 inches.

Luke is now using the Feet scale measurement.

Solving for the area in square inches is shown below:
Area = L * W
Area = (1800 feet *12 inches/1 foot) * (1260 feet *12 inches/1 foot)
Area = 326.592 x10^6 inches²
