Verified step by step guidance

First, calculate the area reserved for housing in acres. Multiply the total area of the ranch, 22.5 million acres, by the percentage reserved for housing, 5.0 x 10^-5%.

Convert the percentage to a decimal by dividing by 100. This gives you the fraction of the total area that is reserved for housing.

Multiply the total area in acres by the decimal fraction to find the area reserved for housing in acres.

Convert the area from acres to square feet using the conversion factor: 1 acre = 43,560 ft².

Convert the area from square feet to square kilometers. First, convert square feet to square miles using the conversion factor: 1 mile = 5280 ft. Then, convert square miles to square kilometers using the conversion factor: 1 km = 0.6214 miles.
