Algebra.Com's Answer #798334 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! draw this. \n" ); document.write( "The length is x \n" ); document.write( "the width is y \n" ); document.write( "The area of the whole rectangle is xy. The perimeter is 2x+2y=300 or x+y=150, so y=150-x \n" ); document.write( "the area of each of the rectangles is x(1/4)y, and this is x(37.5)-x^2. \n" ); document.write( "This quadratic is maximized when x=-b/2a=-37.5/-2 or x=18.75 feet. \n" ); document.write( "That means that 4 of them are 75 feet and the area of the whole rectangle is 75 ft*75 ft=5625 ft^2. It is a square. \r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
