Question

1. which square has a longer side length: a square with an area of 121 units² or a square with sides that are 12 units long?

Explanation:

Step1: Find side of first square

The area of a square is $A = s^2$, so solve for $s$:
$$s = \sqrt{A} = \sqrt{121} = 11$$

Step2: Compare the two side lengths

First square side: 11 units; Second square side: 12 units.
$12 > 11$

Answer:

The square with sides that are 12 units long has a longer side length.
