first.
     find the areas of triangles
            area of a triangle = (base x height )/2
   hence 2 smaller triangles r congruent ... u can find the area of one triangle and multipy them by 2 to get the area of 2 triangles...
       
consider the smaller triangle..
           base = w
           height = y
now wt will be the area ?

hence the 2 smaller triangles r congruent... there sides, bases and heights r equal which means|dw:1382468695484:dw|
