Question

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

A. 2 meters
B. 16 meters
C. 63 meters
D. 65 meters

Answer 1

B. 16 meters

Explanation:

Use Pythagorean Theorem to find the value of x

63² + x² = 65² Simplify

3969 + x² = 4225

-3969 - 3969 Subtract 3969 from both sides

x² = 256 Take the square root of both sides

x = 16

Answer 2

B

Explanation:

Use the pythagorean theorem

a² + b² = c²

a² + 63² = 65²

a² + 3969 = 4225

a² = 256

a = 16

x = 16 meters
