Answer:

12.5

Explanation:

If an isosceles right triangle as the length of the equal sides is a , then the length of the hypotenuse will be a2–√ (using pythogoras theorem.

Hence the perimeter will be a+a+a2–√=a(2+2–√)

Hence the equal sides of the triangle in question has the length of a=5

Area of the triangle = 12∗Height∗Base

=12∗5∗5=12.5
