Answer

27 feet

Work Step by Step

9 yd = 27 feet Use a unit fraction with feet (the unit for your answer) in the numerator, and yards (the unit being changed) in the denominator. Because 3 ft = 1 yard, the necessary unit fraction is (3 ft)/(1 yard) Multiply 9 yard times the unit fraction. 9 * (3 ft)/(1 yard) = 27 feet
