The diagonal of a square is x units. What is the area of the square in terms of x?
12 square units

A = (x^2)/2

Step-by-step explanation:

Represent the length of one side of the square by s.  Then, according to the Pythagorean Theorem,

x^2 = s^2 + s^2, or x^2 = 2s^2, or (solving for s^2), s^2 = (x^2)/2

This last result is the area of the square in terms of x:  A = (x^2)/2

d. 9

step-by-step explanation:

54/12 = 4.5

sf = 4.5

so x = 2 · 4.5 = 9
