a=length 0f equal sides; h=length of hypotenuse=26mm;
Since a is height and base,area=%281%2F2%29a%5E2
2a%5E2=h%5E2
2a%5E2=%2826mm%29%5E2
2a%5E2=676mm%5E2 Divide each side by 2.
a%5E2=338mm%5E2
Area=%281%2F2%29%28a%5E2%29
Area=%281%2F2%29%28338mm%5E2%29
Area=169mm%5E2 ANSWER: The area is 169 sq mm.
