Answer 1

The scale factor of actual foundation to blueprint will be 156 to 1

Explanation:

Here, we want to find the scale factor of the actual foundation to the blueprint

To do this, we need the actual measure of the two to be in the same units

Mathematically, 1 foot = 12 inches

So the number of inches in 52 feet will be 52 * 12 = 624 inches

So scale factor of foundation to blueprint will be;

4 inches to 624 inches

156 to 1
