To find the area of a square with it's diagonal, there's actually a formula = (1/2)d², but here's how to do it if you don't have the formula:
The diagonal <em>c</em> separates the square into two of the same triangles. Therefore, we can apply Pythagorean Theorem
a²+b²=c² ← Since this is a square, a=b is a must
a²+a²=c² ← Combine like terms, and plug 26 in for c
2a²= 26² ← 26²=676, then divide 2 on both sides
a²= 676/2
a²=338 ← We can just stop here! Since <em>a </em>is a side of the square, therefore the area of a square = a²
Answer: 338 units²

Answer:
In triangle DEF:
Given: 
, 
and 
To list the sides of a triangle in order from shortest to longest.
In the Figure as shown below :
If one of the angle of a triangle is larger than, then the sides opposite the larger angle is longer than the side opposite to the shorter
Therefore, the list of the sides of a triangle DEF in order from shortest to longest is,
