Question

Rebecca left her house and walked 2 blocks east. She turned and walked 5 blocks north to get

to the library. How far is the direct route from Rebecca's house to the library?

Answer 1

If you talking about how many blocks she needs to walk, the answer is simple: 5 + 2 = 7

But if you use blocks as a sort of lenght measurement system, it's

`\sqrt{7 {}^(2) + 5 ^(2) }`
