48 <h3>Problem 1</h3>

49 <p>Find the length of the square, where the area of the square is 5041 cm².</p>

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

51 <p>The area of a square = (a2)</p>

52 <p>So, the area of a square = 5041 cm²</p>

53 <p>So, the length = (sqrt{5041} = 71).</p>

54 <p>The length of each side = 71 cm</p>

55 <h3>Explanation</h3>

56 <p>The length of a square is 71 cm.</p>

57 <p>Because the area is 5041 cm², the length is (sqrt{5041} = 71).</p>

58 <p>Well explained 👍</p>

59 <h3>Problem 2</h3>

60 <p>Anna wants to tile her square kitchen floor with a side length of 71 feet. The cost to tile a square foot is 5 dollars. How much will it cost to tile the full floor?</p>

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

62 <p>The length of the floor = 71 feet</p>

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

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

65 <p>Area of the floor = area of the square = (a2)</p>

66 <p>Here (a = 71)</p>

67 <p>Therefore, the area of the floor = (712 = 71 × 71 = 5041).</p>

68 <p>The cost to tile the floor = 5041 × 5 = 25205.</p>

69 <p>The total cost = 25205 dollars</p>

70 <h3>Explanation</h3>

71 <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 25205 dollars.</p>

72 <p>Well explained 👍</p>

73 <h3>Problem 3</h3>

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

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

76 <p>The area of the circle = 15824.06 m²</p>

77 <h3>Explanation</h3>

78 <p>The area of a circle = (pi r2)</p>

79 <p>Here, (r = 71)</p>

80 <p>Therefore, the area of the circle = (pi × 712) = (3.14 × 71 × 71 = 15824.06) m².</p>

81 <p>Well explained 👍</p>

82 <h3>Problem 4</h3>

83 <p>The area of the square is 5041 cm². Find the perimeter of the square.</p>

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

85 <p>The perimeter of the square is 284 cm.</p>

86 <h3>Explanation</h3>

87 <p>The area of the square = (a2)</p>

88 <p>Here, the area is 5041 cm²</p>

89 <p>The length of the side is (sqrt{5041} = 71)</p>

90 <p>Perimeter of the square = 4a Here, (a = 71)</p>

91 <p>Therefore, the perimeter = 4 × 71 = 284 cm.</p>

92 <p>Well explained 👍</p>

93 <h3>Problem 5</h3>

94 <p>Find the square of 72.</p>

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

96 <p>The square of 72 is 5184.</p>

97 <h3>Explanation</h3>

98 <p>The square of 72 is multiplying 72 by 72.</p>

99 <p>So, the square = 72 × 72 = 5184</p>
