<u>Given</u>:
Given that the length of the two legs of the right triangle are 28 m and 45 m.
We need to determine the length of the hypotenuse.
<u>Length of the hypotenuse:</u>
The length of the hypotenuse can be determined using the Pythagorean theorem.
Thus, we have;
Simplifying, we get;
Taking square root on both sides, we get;
Thus, the length of the hypotenuse is 53 m
Hence, Option C is the correct answer.
