You should recognize this as multiple of a 3,4,5 right triangle.
The other side is 8. So 8*6=48 =area

The area of a rectangle is found by multiplying the length by the width. In your example, only the width was given so we need to find the length.
The Pythagorean theorem states that in any right triagle,
Where C is the hypotenuse (or the diagonal)
A and B represent the sides of the triangle but it does not matter which one so We will set A = 6 (the given width)
and C = 10 (hypotenuse)
The equation:
Subtract 36 from both sides
Take the square root of both sides
The length of the retangle is 8
Now we can find the area of the rectangle:
A = L * W
Area = 8 * 6
Area = 48 square units
