Question

what is the missing length? area = 121 yd² s = yards

Explanation:

Step1: Recall area formula for square

The area formula for a square is $A = s^2$, where $A$ is the area and $s$ is the side - length.

Step2: Solve for $s$

Given $A = 121$ yd², we have $s^2=121$. Taking the square root of both sides, $s=\sqrt{121}$. Since length cannot be negative in this context, $s = 11$ yards.

Answer:

11
