Hello!

You can use the Pythagorean Theorem to solve this

Separate the rectangle into two triangles

$a^{2} + b^{2} = c^{2}$

c is the diagonal
a and b are the side lengths

Put in the values you know

$5^{2} + 4^{2} = c^{2}$

Square the numbers

$25 + 16 = c^{2}$

Add

$41 = c^{2}$

Take the square root of both sides

6.4 = c

The answer is B) 6.4 units

Hope this helps!
