Best ResponseYou've already chosen the best response.2Ok see let the equal sides each be x and base be b 2*x + b=36 and x^2 =(b/2)^2 + 6^2 (Pythagoras theorem) from the first equation x=(36b)/2 square and substitute in the second equartion you get base =18 and x=9 hence you know the sides substitute in the formula area=1/2*base*height you get 1/2 * 18 * 6=54
