Question

ABCD is a rectangle. What is the value of x?

Answer 1

Step-by-step explanation:

Using Pythagoras Theorem

AC²=AB²+BC²

65²=63²+x²

x²=65²-63²m

x²=256

x=16

Option B

Answer 2

$AC^{2} = AB^{2} + BC^{2}$ (Pythagorean theorem)

$65^{2} = 63^{2} + x^{2}$

4225 = 3969 + $x^{2}$

$x^{2} = 4225 - 3969$

$x^{2} = 256$

x = $\sqrt{256}$

x = 16 meters

B) 16 meters
