Question

The length of a rectangle is 6 units and its width is 4 units. What is the approximate length of the diagonal of the rectangle? (5 points)

2 units
4.4 units
6 units
7.2 units

Answer 1

7.2 or d

Explanation:

Answer 2

Use the Pythagorean Theorem.  6^2 + 4^2 = d^2, where d is the diagonal length.  Then d^2 = 36+16 = 52, and d = sqrt(52), or a little over 7 units.
