46 <h3>Problem 1</h3>

47 <p>Find the length of the square, where the area of the square is 14641 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 = 14641 cm²</p>

51 <p>So, the length = √14641 = 121.</p>

52 <p>The length of each side = 121 cm</p>

53 <h3>Explanation</h3>

54 <p>The length of a square is 121 cm. Because the area is 14641 cm² the length is √14641 = 121.</p>

55 <p>Well explained 👍</p>

56 <h3>Problem 2</h3>

57 <p>Sarah is planning to tile her square floor of length 121 feet. The cost to tile a foot is 5 dollars. How much will it cost to tile the full floor?</p>

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

59 <p>The length of the floor = 121 feet</p>

60 <p>The cost to tile 1 square foot of floor = 5 dollars.</p>

61 <p>To find the total cost to tile, we find the area of the floor,</p>

62 <p>Area of the floor = area of the square = a²</p>

63 <p>Here a = 121</p>

64 <p>Therefore, the area of the floor = 121² = 121 × 121 = 14641.</p>

65 <p>The cost to tile the floor = 14641 × 5 = 73205.</p>

66 <p>The total cost = 73205 dollars</p>

67 <h3>Explanation</h3>

68 <p>To find the cost to tile the floor, we multiply the area of the floor by the cost to tile per foot. So, the total cost is 73205 dollars.</p>

69 <p>Well explained 👍</p>

70 <h3>Problem 3</h3>

71 <p>Find the area of a circle whose radius is 121 meters.</p>

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

73 <p>The area of the circle = 45931.5 m²</p>

74 <h3>Explanation</h3>

75 <p>The area of a circle = πr²</p>

76 <p>Here, r = 121</p>

77 <p>Therefore, the area of the circle = π × 121² = 3.14 × 121 × 121 = 45931.5 m².</p>

78 <p>Well explained 👍</p>

79 <h3>Problem 4</h3>

80 <p>The area of the square is 14641 cm². Find the perimeter of the square.</p>

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

82 <p>The perimeter of the square is 484 cm.</p>

83 <h3>Explanation</h3>

84 <p>The area of the square = a²</p>

85 <p>Here, the area is 14641 cm²</p>

86 <p>The length of the side is √14641 = 121</p>

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

88 <p>Here, a = 121</p>

89 <p>Therefore, the perimeter = 4 × 121 = 484.</p>

90 <p>Well explained 👍</p>

91 <h3>Problem 5</h3>

92 <p>Find the square of 122.</p>

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

94 <p>The square of 122 is 14884.</p>

95 <h3>Explanation</h3>

96 <p>The square of 122 is multiplying 122 by 122.</p>

97 <p>So, the square = 122 × 122 = 14884.</p>
