46 <h3>Problem 1</h3>

47 <p>Find the length of the square, where the area of the square is 239,121 cm².</p>

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

49 <p>The area of a square = a²</p>

50 <p>So, the area of a square = 239,121 cm²</p>

51 <p>So, the length = √239,121 = 489.</p>

52 <p>The length of each side = 489 cm</p>

53 <h3>Explanation</h3>

54 <p>The length of a square is 489 cm. Because the area is 239,121 cm² the length is √239,121 = 489.</p>

55 <p>Well explained 👍</p>

56 <h3>Problem 2</h3>

57 <p>Sarah is planning to wallpaper her square wall of length 489 feet. The cost to wallpaper a foot is 3 dollars. Then how much will it cost to wallpaper the full wall?</p>

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

59 <p>The length of the wall = 489 feet The cost to wallpaper 1 square foot of wall = is 3 dollars. To find the total cost to wallpaper, we find the area of the wall, Area of the wall = area of the square = a² Here a = 489 Therefore, the area of the wall = 489² = 489 × 489 = 239,121. The cost to wallpaper the wall = 239,121 × 3 = 717,363. The total cost = 717,363 dollars</p>

60 <h3>Explanation</h3>

61 <p>To find the cost to wallpaper the wall, we multiply the area of the wall by the cost to wallpaper per foot. So, the total cost is 717,363 dollars.</p>
