1. The diagonal of the floor of a rectangular closet is7 $$\frac { 1 } { 2 }$$ feet. The shorter side of the closet is 4$$\frac { 1 } { 2 }$$feet. What is the area of the closet in square feet?

2.  A. 5$$\frac { 1 } { 4 }$$ B. 13$$\frac { 1 } { 2 }$$ C. 27 D. 37

Explanation :

Other side=$${\sqrt{[15/2}-[9/2 ]^2 } { }$$ft

=$${\sqrt{225/4}-81/4 } { }$$ft

=$${\sqrt{144/4} } { }$$ ft

=6 ft

Area of closet = (6 x 4.5) sq. ft = 27 sq. ft.
