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( "
