18 <h3>Problem 1</h3>

19 <p>Find the length of the square, where the area of the square is 11025 cm².</p>

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

21 <p>The area of a square = a² So, the area of a square = 11025 cm² So, the length = √11025 = 105. The length of each side = 105 cm</p>

22 <h3>Explanation</h3>

23 <p>The length of a square is 105 cm. Because the area is 11025 cm², the length is √11025 = 105.</p>

24 <p>Well explained 👍</p>

25 <h3>Problem 2</h3>

26 <p>Sarah is planning to paint her square garden wall of length 105 feet. The cost to paint a foot is 2 dollars. Then how much will it cost to paint the full wall?</p>

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

28 <p>The length of the wall = 105 feet The cost to paint 1 square foot of wall = 2 dollars. To find the total cost to paint, we find the area of the wall, Area of the wall = area of the square = a² Here a = 105 Therefore, the area of the wall = 105² = 105 × 105 = 11025. The cost to paint the wall = 11025 × 2 = 22050. The total cost = 22050 dollars</p>

29 <h3>Explanation</h3>

30 <p>To find the cost to paint the wall, we multiply the area of the wall by the cost to paint per foot. So, the total cost is 22050 dollars.</p>
