Algebra.Com's Answer #500893 by JulietG(1812)![]() ![]() You can put this solution on YOUR website! You have to make the assumption first that the lot is a rectangle. \n" ); document.write( "In that case, you'll use the formula for Area. Area = Width * Length. \n" ); document.write( "We know the area, and we know the width. \n" ); document.write( "Where most people will get this wrong is not catching that the measurements are different. First, we need to convert ft to yards. (3 feet in a yard.) The *new* measurement of street frontage is 15 (45/3) \n" ); document.write( "Now we can plug in the values and find the other measurement. \n" ); document.write( ". \n" ); document.write( "Area (1280) = Length (x) * Width (15) \n" ); document.write( "1280 = 15x \n" ); document.write( "Divide each side by 15 \n" ); document.write( "length = 85 1/3 yards \n" ); document.write( ". \n" ); document.write( "Since it's \"1/3\", I'm suspecting your teacher wants the answer in feet. So we'll convert back by multiplying 85 1/3 yards by 3 feet in a yard. \n" ); document.write( "3 * 85.33 = 256 feet \n" ); document.write( " \n" ); document.write( " |
