Answer:

A = 98 sq. meters

Step-by-step explanation:

angle in a 45 - 45 - 90 right triangle  the hypotenuse = leg([tex]\sqrt{2}[/tex] ).

So hypotenuse is opposite the 90°  angle = 14[tex]\sqrt{2}[/tex]

  hypotenuse = leg([tex]\sqrt{2}[/tex] )

     14[tex]\sqrt{2}[/tex] = x([tex]\sqrt{2}[/tex] )

       14[tex]\sqrt{2}[/tex] / [tex]\sqrt{2}[/tex]  = x

         14 = x

       or

      a² + b² = c²

      x² + x² = (14[tex]\sqrt{2}[/tex] )²    Both of the legs in this type of triangle are =

       2x² =  196 ([tex]\sqrt{4}[/tex] )

        2x² = 196(2)

        2x² = 392

         x²  = 196

         x = [tex]\sqrt{196}[/tex]

         x = 14

  A = 1/2bh

   A = .5(14)(14)

   A = 98 sq. meters
