Squaring Up
Assume you want to “square-up” forms
for a concrete foundation measuring 45
feet 6 inches by 24 feet 4 inches. In order
for the forms to be square, what should
both of the diagonal measurements be?
(You can use the Pythagorean theorem to
solve the next problems. See the diagram
after "Common Rafter" on page 36.)
