Please help me on this problem!

A = 98 sq. meters

Step-by-step explanation:

angle in a 45 - 45 - 90 right triangle  the hypotenuse = leg( ).

So hypotenuse is opposite the 90°  angle = 14

  hypotenuse = leg( )

     14 = x( )

       14 /  = x

         14 = x

       or

      a² + b² = c²

      x² + x² = (14 )²    Both of the legs in this type of triangle are =

       2x² =  196 ( )

        2x² = 196(2)

        2x² = 392

         x²  = 196

         x =

         x = 14

  A = 1/2bh

   A = .5(14)(14)

   A = 98 sq. meters
