40 <h3>Problem 1</h3>

41 <p>Find the length of the square, where the area of the square is 720801 cm².</p>

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

43 <p>The area of a square = a²</p>

44 <p>So, the area of a square = 720801 cm²</p>

45 <p>So, the length = √720801 = 849.</p>

46 <p>The length of each side = 849 cm</p>

47 <h3>Explanation</h3>

48 <p>The length of a square is 849 cm.</p>

49 <p>Because the area is 720801 cm²</p>

50 <p>the length is √720801 = 849.</p>

51 <p>Well explained 👍</p>

52 <h3>Problem 2</h3>

53 <p>Julia wants to tile her square floor of length 849 feet. The cost to tile a foot is 5 dollars. How much will it cost to tile the full floor?</p>

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

55 <p>The length of the floor = 849 feet</p>

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

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

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

59 <p>Here a = 849</p>

60 <p>Therefore, the area of the floor = 849² = 849 × 849 = 720801.</p>

61 <p>The cost to tile the floor = 720801 × 5 = 3604005.</p>

62 <p>The total cost = 3604005 dollars</p>

63 <h3>Explanation</h3>

64 <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 3604005 dollars.</p>

66 <h3>Problem 3</h3>

67 <p>Find the area of a circle whose radius is 849 meters.</p>

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

69 <p>The area of the circle = 2269823.06 m²</p>

70 <h3>Explanation</h3>

71 <p>The area of a circle = πr²</p>

72 <p>Here, r = 849</p>

73 <p>Therefore, the area of the circle = π × 849² = 3.14 × 849 × 849 = 2269823.06 m².</p>

74 <p>Well explained 👍</p>

75 <h3>Problem 4</h3>

76 <p>The area of the square is 720801 cm². Find the perimeter of the square.</p>

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

78 <p>The perimeter of the square is 3396 cm</p>

79 <h3>Explanation</h3>

80 <p>The area of the square = a²</p>

81 <p>Here, the area is 720801 cm²</p>

82 <p>The length of the side is √720801 = 849</p>

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

84 <p>Here, a = 849</p>

85 <p>Therefore, the perimeter = 4 × 849 = 3396 cm.</p>

86 <p>Well explained 👍</p>

87 <h3>Problem 5</h3>

88 <p>Find the square of 850.</p>

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

90 <p>The square of 850 is 722500</p>

91 <h3>Explanation</h3>

92 <p>The square of 850 is multiplying 850 by 850.</p>

93 <p>So, the square = 850 × 850 = 722500</p>
