The diagonal of the floor of a rectangular closet is `7 1/2` feet. he shorter side of the closet is `4 1/2` feet. What is the area of he closet in square feet ?
Other side = `sqrt((15/2)^2 - (9/2)^2)` ft
=`sqrt((225)/(4) - (81)/(4))` ft
=`sqrt(144/4)` ft = 6 ft.
`:.` Area of the closet = (6 x 4.5) sq.ft. = 27 sq.ft.
