Place the ladder of lenght L up against the wall. Then the window will be (L-1) feet high. Now place the ladder 7 feet from the base of the wall, and you get a right triangle with hypotenuse of L and two legs of 7 and (L - 1). Use the Pythagorean theorem to get
\n" ); document.write( "(1) L^2 = 7^2 + (L-1)^2 or
\n" ); document.write( "(2) L^2 = 49 + L^2 -2*L + 1 or
\n" ); document.write( "(3) 2*L = 50 or
\n" ); document.write( "(4) L = 25
\n" ); document.write( "Answer: The length of the ladder is 25 feet. and the window is 24 feet high.
