Asquare is cut in half on the diagonal creating two equal triangle. each triangle has an are of 1.32 square units. what is the side length in unit of the orginial square

What is the side length in unit of the original square?

Let's start by getting the area of the square.
The area of the square is the sum of the areas of the two triangles, or
2 x 1,32  = 2.64 square units.
Now, all sides of a square are the same length. That is the length we need, let's call that length L.
So, the area of the square is L x L = 2.64 square units, which is the same as the square root of 2.64

B? ? i'm most likely wrong but i think it would be b
