4: Find the diagonal of a square whose area is 36.
A. 6
B. 6√2
C. 9
D. 9 √2 - answer B. 6√2
B. The area of a square is s2 where s is a side of the square. If s2 = 36, then s = 6. The diagonal
of a square forms two right triangles; d is the hypotenuse and the two legs are 6 units long.
Using the Pythagorean theorem, d2 = 62 + 62 = 36 + 36 = 72. Therefore, d = √72 = 6√2.
