Question

Which of the numbers between 220 and 300 have perfect square roots?

• A. 225
• B. 269
• C. 289
• D. 256

Answer 1

Answer: (A), (C), (D)

The correct options are
A

225

C

289

D

256

For the chosen answers, we have,

225 = 15 $\times$ 15 = ${15}^2$

256 = 16 $\times$ 16 = ${16}^2$

289 = 17 $\times$ 17 = ${17}^2$

So all three choices are perfect squares of 15, 16, and 17. And they are within the given numbers 220 and 300.
