I remember that the square of 12 is 144.
Let's work up from there to the squares that 180 lies between.
Keep in mind that squares are when a number multiplies by itself.
For example;
10^2 means 10 • 10, which makes the product of 100.
12^2 = 144
13^2 = 169
14^2 = 196
Well, we have 169 and 196, which 180 lies between.
Your answers are:
13 and 14.
I hope this helps!
