41 <h3>Problem 1</h3>

42 <p>Find the length of the square, where the area of the square is 423,801 cm².</p>

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

44 <p>The area of a square = a²</p>

45 <p>So, the area of a square = 423,801 cm²</p>

46 <p>So, the length = √423,801 = 651.</p>

47 <p>The length of each side = 651 cm</p>

48 <h3>Explanation</h3>

49 <p>The length of a square is 651 cm. Because the area is 423,801 cm² the length is √423,801 = 651.</p>

50 <p>Well explained 👍</p>

51 <h3>Problem 2</h3>

52 <p>Sarah wants to tile her square room, which is 651 feet on each side. The cost to tile a square foot is 5 dollars. How much will it cost to tile the entire room?</p>

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

54 <p>The length of the room = 651 feet</p>

55 <p>The cost to tile 1 square foot of the room = 5 dollars.</p>

56 <p>To find the total cost to tile, we find the area of the room,</p>

57 <p>Area of the room = area of the square = a²</p>

58 <p>Here a = 651</p>

59 <p>Therefore, the area of the room = 651² = 651 × 651 = 423,801.</p>

60 <p>The cost to tile the room = 423,801 × 5 = 2,119,005.</p>

61 <p>The total cost = 2,119,005 dollars</p>

62 <h3>Explanation</h3>

63 <p>To find the cost to tile the room, we multiply the area of the room by the cost to tile per foot. So, the total cost is 2,119,005 dollars.</p>

64 <p>Well explained 👍</p>

65 <h3>Problem 3</h3>

66 <p>Find the area of a circle whose radius is 651 meters.</p>

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

68 <p>The area of the circle = 1,331,601.86 m²</p>

69 <h3>Explanation</h3>

70 <p>The area of a circle = πr²</p>

71 <p>Here, r = 651</p>

72 <p>Therefore, the area of the circle = π × 651² = 3.14 × 651 × 651 = 1,331,601.86 m².</p>

73 <p>Well explained 👍</p>

74 <h3>Problem 4</h3>

75 <p>The area of the square is 423,801 cm². Find the perimeter of the square.</p>

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

77 <p>The perimeter of the square is 2,604 cm.</p>

78 <h3>Explanation</h3>

79 <p>The area of the square = a²</p>

80 <p>Here, the area is 423,801 cm²</p>

81 <p>The length of the side is √423,801 = 651</p>

82 <p>Perimeter of the square = 4a</p>

83 <p>Here, a = 651</p>

84 <p>Therefore, the perimeter = 4 × 651 = 2,604.</p>

85 <p>Well explained 👍</p>

86 <h3>Problem 5</h3>

87 <p>Find the square of 652.</p>

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

89 <p>The square of 652 is 425,104.</p>

90 <h3>Explanation</h3>

91 <p>The square of 652 is multiplying 652 by 652.</p>

92 <p>So, the square = 652 × 652 = 425,104.</p>
