Question

1. titus wants to fence a square area of his yard for his dogs. if he wants the area of the square to be 121 square feet, what does the perimeter of the square need to be?

Explanation:

Step1: Find side - length of square

Let side - length be $s$. Area of square $A = s^{2}$. Given $A = 121$ square feet, so $s^{2}=121$, then $s=\sqrt{121}=11$ feet.

Step2: Calculate perimeter of square

Perimeter of square $P = 4s$. Substitute $s = 11$ feet, so $P=4\times11 = 44$ feet.

Answer:

44 feet
