44 <h3>Problem 1</h3>

45 <p>Find the length of the square, where the area of the square is 13,847,041 cm².</p>

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

47 <p>The area of a square = a²</p>

48 <p>So, the area of a square = 13,847,041 cm²</p>

49 <p>So, the length = √13,847,041 = 3721.</p>

50 <p>The length of each side = 3721 cm</p>

51 <h3>Explanation</h3>

52 <p>The length of a square is 3721 cm.</p>

53 <p>Because the area is 13,847,041 cm² the length is √13,847,041 = 3721.</p>

54 <p>Well explained 👍</p>

55 <h3>Problem 2</h3>

56 <p>Sarah wants to install a square-shaped garden with a length of 3721 feet. The cost to install per square foot is 5 dollars. How much will it cost to install the entire garden?</p>

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

58 <p>The length of the garden = 3721 feet</p>

59 <p>The cost to install 1 square foot of garden = 5 dollars.</p>

60 <p>To find the total cost to install, we find the area of the garden,</p>

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

62 <p>Here a = 3721</p>

63 <p>Therefore, the area of the garden = 3721² = 13,847,041.</p>

64 <p>The cost to install the garden = 13,847,041 × 5 = 69,235,205.</p>

65 <p>The total cost = 69,235,205 dollars</p>

66 <h3>Explanation</h3>

67 <p>To find the cost to install the garden, we multiply the area of the garden by the cost to install per foot.</p>

68 <p>So, the total cost is 69,235,205 dollars.</p>

69 <p>Well explained 👍</p>

70 <h3>Problem 3</h3>

71 <p>Find the area of a circle whose radius is 3721 meters.</p>

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

73 <p>The area of the circle = 43,478,484.22 m²</p>

74 <h3>Explanation</h3>

75 <p>The area of a circle = πr²</p>

76 <p>Here, r = 3721</p>

77 <p>Therefore, the area of the circle = π × 3721² = 3.14 × 3721 × 3721 = 43,478,484.22 m².</p>

78 <p>Well explained 👍</p>

79 <h3>Problem 4</h3>

80 <p>The area of the square is 13,847,041 cm². Find the perimeter of the square.</p>

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

82 <p>The perimeter of the square is</p>

83 <h3>Explanation</h3>

84 <p>The area of the square = a²</p>

85 <p>Here, the area is 13,847,041 cm²</p>

86 <p>The length of the side is √13,847,041 = 3721</p>

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

88 <p>Here, a = 3721</p>

89 <p>Therefore, the perimeter = 4 × 3721 = 14,884.</p>

90 <p>Well explained 👍</p>

91 <h3>Problem 5</h3>

92 <p>Find the square of 3722.</p>

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

94 <p>The square of 3722 is 13,855,684</p>

95 <h3>Explanation</h3>

96 <p>The square of 3722 is multiplying 3722 by 3722.</p>

97 <p>So, the square = 3722 × 3722 = 13,855,684</p>

98 <p>Well explained 👍</p>
