maverick08 Posted November 12, 2008 Share Posted November 12, 2008 Quadrilateral RSTU shown above is a site plan for a parking lot in which side RU is parallel to side ST and RU is longer than ST. What is the area of the parking lot ? (1) RU = 80 meters (2) TU= 20 sqrt(10) meters The figure is attached in the word doc. The answer I went with was A. But the OA is different. If anyone differs, then please explain. Thanks Quote Link to comment Share on other sites More sharing options...
supersuj Posted November 12, 2008 Share Posted November 12, 2008 I get D Statement (1) RU=80 area=1/2*(80+45)*60.......SUFFICIENT Statement (2) Drop a perpendicular line from T on RU, and lets call that point X RW=15, WX=45, TX=60, TU=20sqrt(10) Apply Pythag theorem, we get TX^2 + XU^2 = TU^2 Solving, we get XU=20, hence RU=80 Area= same as statement 1...............SUFFICIENT Quote Link to comment Share on other sites More sharing options...
