Question

ABCD is a rectangle. Find the length of each diagonal.

Answer 1

Answer: The correct answer is 3

Explanation:

C = 3

AC = 3/3 = 1

BD = 4 - 3 = 1

Answer 2

The diagonals of a rectangle are congruent, so AC = BD

c/3 = 4-c
с = 3(4-с)
с = 12 - 3с
с + 3с = 12
4с = 12
с = 12/4
с = 3

АС = с/3 = 3/3 = 1
BD = 4 - с = 4 - 3 = 1

The length of each diagonal = 1
