Question

The length of the diagonal of a square is 14. What is the length of each side?

Answer 1

answers:
7sqrt2
14sqrt2
7sqrt3

Answer 2

a^2 + b^2 = c^2

Answer 3

in a square, a = b sooo

b^2 + b^2 = c^2

2b^2 = c^2

b^2 = c^2/2

b = c/sqrt(2)

Answer 4

but it looks like they modified the results such that:

c sqrt(2)/2 would suffice

Answer 5

14 sqrt 2???? Im so confused

Answer 6

it just the pythagorean thrm

Answer 7

but since c = 14

14 sqrt(2)/2 would simplify to your answer

Answer 8

Iknow the pathagorean therum but im not familiar with radicals

Answer 9

what is 14/2 ?

Answer 10

7

Answer 11

then we get 7 sqrt(2) does that match an answer choice?
