A rectangular room has the rectangular shaped rug shown as above figure such that the rug’s area is 220 square feet and its length is 12 feet longer than its width. If the uniform width between the rug and room is 12 feet, what is the area of the region uncovered by the rug (shaded region), in square feet?	Choose the correct choice from the following
A) 32  B) 1136  C) 40  D) 1344  E) 104
Rug's area = 220   which is (x) x (12+x) = 220   so x= 10   rug maintains a uniform distance of 12 feet   so room has dimension 10+24 and 22+24 i.e. 34 and 46   area of room 34x46 = 1564   area covered is 120   so uncovered area is 1564-220=
