Question

If ABCD is a square and AB = 10, what is the measure of BD? (rounded to the

nearest hundredth)
A)
7.07
14.14
19.21
28.28

Answer 1

CE ≈ 7.07

Explanation:

you have to use the formula

Answer 2

14.14

Explanation:

AB=10 units then BC=10 units, CD=10 units and AD=10 units because it's a square

BD is diagonal which by using Pythagoras theorem

`BD=\sqrt {AB^(2)+AD^(2)}=\sqrt {10^(2)+10^(2)}\approx 14.14 units`
