41 <h3>Problem 1</h3>

42 <p>Find the length of the square, where the area of the square is 178,929 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 = 178,929 cm²</p>

46 <p>So, the length = √178,929 = 423.</p>

47 <p>The length of each side = 423 cm</p>

48 <h3>Explanation</h3>

49 <p>The length of a square is 423 cm. Because the area is 178,929 cm², the length is √178,929 = 423.</p>

50 <p>Well explained 👍</p>

51 <h3>Problem 2</h3>

52 <p>Sarah wants to cover her square garden of length 423 feet with grass. The cost to cover a square foot is 2 dollars. Then how much will it cost to cover the full garden?</p>

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

54 <p>The length of the garden = 423 feet</p>

55 <p>The cost to cover 1 square foot of garden = 2 dollars.</p>

56 <p>To find the total cost to cover, we find the area of the garden,</p>

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

58 <p>Here a = 423</p>

59 <p>Therefore, the area of the garden = 423² = 423 × 423 = 178,929.</p>

60 <p>The cost to cover the garden = 178,929 × 2 = 357,858.</p>

61 <p>The total cost = 357,858 dollars</p>

62 <h3>Explanation</h3>

63 <p>To find the cost to cover the garden, we multiply the area of the garden by the cost to cover per foot. So, the total cost is 357,858 dollars.</p>

64 <p>Well explained 👍</p>

65 <h3>Problem 3</h3>

66 <p>Find the area of a circle whose radius is 423 meters.</p>

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

68 <p>The area of the circle = 561,990.51 m²</p>

69 <h3>Explanation</h3>

70 <p>The area of a circle = πr²</p>

71 <p>Here, r = 423</p>

72 <p>Therefore, the area of the circle = π × 423² = 3.14 × 423 × 423 = 561,990.51 m².</p>

73 <p>Well explained 👍</p>

74 <h3>Problem 4</h3>

75 <p>The area of the square is 178,929 cm². Find the perimeter of the square.</p>

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

77 <p>The perimeter of the square is 1,692 cm.</p>

78 <h3>Explanation</h3>

79 <p>The area of the square = a²</p>

80 <p>Here, the area is 178,929 cm²</p>

81 <p>The length of the side is √178,929 = 423</p>

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

83 <p>Here, a = 423</p>

84 <p>Therefore, the perimeter = 4 × 423 = 1,692.</p>

85 <p>Well explained 👍</p>

86 <h3>Problem 5</h3>

87 <p>Find the square of 424.</p>

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

89 <p>The square of 424 is 179,776.</p>

90 <h3>Explanation</h3>

91 <p>The square of 424 is multiplying 424 by 424.</p>

92 <p>So, the square = 424 × 424 = 179,776.</p>
