18 <h3>Problem 1</h3>

19 <p>Find the side length of a square, where the area of the square is 121,801 cm².</p>

20 <p>Okay, lets begin</p>

21 <p>The area of a square = a² So, the area of a square = 121,801 cm² So, the length = √121,801 = 349. The length of each side = 349 cm</p>

22 <h3>Explanation</h3>

23 <p>The length of a square is 349 cm. Because the area is 121,801 cm², the length is √121,801 = 349.</p>

24 <p>Well explained 👍</p>

25 <h3>Problem 2</h3>

26 <p>Sarah is planning to paint her square-shaped garden fence of length 349 feet. The cost to paint a foot is 5 dollars. Then how much will it cost to paint the full fence?</p>

27 <p>Okay, lets begin</p>

28 <p>The length of the fence = 349 feet The cost to paint 1 square foot of fence = 5 dollars. To find the total cost to paint, we find the area of the fence, Area of the fence = area of the square = a² Here a = 349 Therefore, the area of the fence = 349² = 349 × 349 = 121,801. The cost to paint the fence = 121,801 × 5 = 609,005. The total cost = 609,005 dollars</p>

29 <h3>Explanation</h3>

30 <p>To find the cost to paint the fence, we multiply the area of the fence by the cost to paint per foot. So, the total cost is 609,005 dollars.</p>
