The area of a rectangle is 14 square meters. Find the length and width of the rectangle if its length is 5 meters greater than its width. Use an equation and the formula for the Area of a rectangle= (width)(length).
\n" ); document.write( "----
\n" ); document.write( "Let the width be \"x\" meters.
\n" ); document.write( "Then the length is \"x+5\" meters.
\n" ); document.write( "----
\n" ); document.write( "Equation:
\n" ); document.write( "A = w*L
\n" ); document.write( "14 = x(x+5)
\n" ); document.write( "14 = x^2+5x
\n" ); document.write( "x^2+5x-14 = 0
\n" ); document.write( "Factor:
\n" ); document.write( "(x+7)(x-2) = 0
\n" ); document.write( "x = -7 of x = 2
\n" ); document.write( "---
\n" ); document.write( "Only the positive solution is meaningful.
\n" ); document.write( "width = 2 meters
\n" ); document.write( "length = 7 meters
\n" ); document.write( "===================
