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 two problems. See the dia-
gram at the bottom of the next page.)
