Jennifer has a square bedroom. the area of her room is 144 ft2. what is the length of one side of jennifer’s room?
a 10 ft
b 12 ft
c 18 ft
d 36 ft

B.) 12 ft

Step-by-step explanation:

A square's sides are all the same: meaning, every side MUST be the same length. Then, all we have to do is find the square root of 144, which is 12.

To check this, we need to multiply the length times the height. If it equals 144, it is correct.

12 x 12 = 144

Hope I explained this well enough! If this seems confusing, or if you haven't learned square roots yet, you can always just try multiplying down the list of available choices to see what equals 144 c:

( 10 x 10 = 100, 12 x 12 = 144, 18 x 18 = 324, 36 x 36 = 936)
