47 <h3>Problem 1</h3>

48 <p>Find the length of the square, where the area of the square is 59,049 cm².</p>

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

50 <p>The area of a square = a² So, the area of a square = 59,049 cm² So, the length = √59,049 = 243. The length of each side = 243 cm</p>

51 <h3>Explanation</h3>

52 <p>The length of a square is 243 cm.</p>

53 <p>Because the area is 59,049 cm², the length is √59,049 = 243.</p>

54 <p>Well explained 👍</p>

55 <h3>Problem 2</h3>

56 <p>A farmer wants to fence a square plot of land with a side length of 243 meters. The cost to fence one meter is 5 dollars. How much will it cost to fence the entire plot?</p>

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

58 <p>The length of the plot = 243 meters The cost to fence 1 meter of plot = 5 dollars. To find the total cost to fence, we find the perimeter of the plot, Perimeter of the plot = 4a Here a = 243 Therefore, the perimeter of the plot = 4 × 243 = 972. The cost to fence the plot = 972 × 5 = 4,860. The total cost = 4,860 dollars</p>

59 <h3>Explanation</h3>

60 <p>To find the cost to fence the plot, we multiply the perimeter of the plot by the cost to fence per meter</p>

61 <p>So, the total cost is 4,860 dollars.</p>

62 <p>Well explained 👍</p>

63 <h3>Problem 3</h3>

64 <p>Find the area of a circle whose radius is 243 meters.</p>

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

66 <p>The area of the circle = 185,041.5 m²</p>

67 <h3>Explanation</h3>

68 <p>The area of a circle = πr²</p>

69 <p>Here, r = 243</p>

70 <p>Therefore, the area of the circle = π × 243² = 3.14 × 243 × 243 = 185,041.5 m².</p>

71 <p>Well explained 👍</p>

72 <h3>Problem 4</h3>

73 <p>The area of the square is 59,049 cm². Find the perimeter of the square.</p>

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

75 <p>The perimeter of the square is 972 cm</p>

76 <h3>Explanation</h3>

77 <p>The area of the square = a²</p>

78 <p>Here, the area is 59,049 cm²</p>

79 <p>The length of the side is √59,049 = 243</p>

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

81 <p>Here, a = 243</p>

82 <p>Therefore, the perimeter = 4 × 243 = 972 cm.</p>

83 <p>Well explained 👍</p>

84 <h3>Problem 5</h3>

85 <p>Find the square of 244.</p>

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

87 <p>The square of 244 is 59,536</p>

88 <h3>Explanation</h3>

89 <p>The square of 244 is multiplying 244 by 244.</p>

90 <p>So, the square = 244 × 244 = 59,536</p>

91 <p>Well explained 👍</p>
