Answer: 69.4

Explanation:
You need to use the Pythagorean theorem, which is a²+b²=c².
A and B are the legs, and C is the hypotenuse.

So first, we substitute A and B since we know what they are:
47²+51²=c²

Then, we solve using a calculator:
2209+2601=c²

Now, add the two together:
4810=c²

To solve this equation, you have to do the opposite of a square, which is a square root, so now we will find the square root of 4810:

Square root of 4810 is 69.35416

Finally, since you are asked to round to the nearest tenth, your answer is 69.4.
