44 <h3>Problem 1</h3>

45 <p>Find the length of the square, where the area of the square is 293,764 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 = 293,764 cm²</p>

49 <p>So, the length = √293,764 = 542.</p>

50 <p>The length of each side = 542 cm</p>

51 <h3>Explanation</h3>

52 <p>The length of a square is 542 cm.</p>

53 <p>Because the area is 293,764 cm² the length is √293,764 = 542.</p>

54 <p>Well explained 👍</p>

55 <h3>Problem 2</h3>

56 <p>Lisa wants to carpet her square room with a side length of 542 inches. The cost to carpet a square inch is 2 dollars. How much will it cost to carpet the full room?</p>

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

58 <p>The length of the room = 542 inches</p>

59 <p>The cost to carpet 1 square inch of the room = 2 dollars.</p>

60 <p>To find the total cost to carpet, we find the area of the room,</p>

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

62 <p>Here a = 542</p>

63 <p>Therefore, the area of the room = 542² = 542 × 542 = 293,764.</p>

64 <p>The cost to carpet the room = 293,764 × 2 = 587,528.</p>

65 <p>The total cost = 587,528 dollars</p>

66 <h3>Explanation</h3>

67 <p>To find the cost to carpet the room, we multiply the area of the room by the cost to carpet per square inch.</p>

68 <p>So, the total cost is 587,528 dollars.</p>

70 <h3>Problem 3</h3>

71 <p>Find the area of a circle whose radius is 542 meters.</p>

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

73 <p>The area of the circle = 923,628.32 m²</p>

74 <h3>Explanation</h3>

75 <p>The area of a circle = πr² Here, r = 542 Therefore, the area of the circle = π × 542² = 3.14 × 542 × 542 = 923,628.32 m².</p>

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

80 <p>The perimeter of the square is 2,168 cm.</p>

81 <h3>Explanation</h3>

82 <p>The area of the square = a² Here, the area is 293,764 cm² The length of the side is √293,764 = 542 Perimeter of the square = 4a Here, a = 542 Therefore, the perimeter = 4 × 542 = 2,168.</p>

83 <p>Well explained 👍</p>

84 <h3>Problem 5</h3>

85 <p>Find the square of 543.</p>

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

87 <p>The square of 543 is 294,849</p>

88 <h3>Explanation</h3>

89 <p>The square of 543 is multiplying 543 by 543. So, the square = 543 × 543 = 294,849</p>
