46 <h3>Problem 1</h3>

47 <p>Find the length of the square, where the area of the square is 690,561 cm².</p>

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

49 <p>The area of a square = a² So, the area of a square = 690,561 cm² So, the length = √690,561 = 831. The length of each side = 831 cm.</p>

50 <h3>Explanation</h3>

51 <p>The length of a square is 831 cm.</p>

52 <p>Because the area is 690,561 cm², the length is √690,561 = 831.</p>

53 <p>Well explained 👍</p>

54 <h3>Problem 2</h3>

55 <p>Sarah is planning to lay tiles on her square garden with a length of 831 feet. The cost to lay tiles per square foot is 5 dollars. How much will it cost to tile the full garden?</p>

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

57 <p>The length of the garden = 831 feet The cost to lay tiles per square foot = 5 dollars. To find the total cost to tile, we find the area of the garden, Area of the garden = area of the square = a² Here a = 831 Therefore, the area of the garden = 831² = 831 × 831 = 690,561. The cost to tile the garden = 690,561 × 5 = 3,452,805. The total cost = 3,452,805 dollars.</p>

58 <h3>Explanation</h3>

59 <p>To find the cost to tile the garden, we multiply the area of the garden by the cost to tile per foot.</p>

60 <p>So, the total cost is 3,452,805 dollars.</p>

61 <p>Well explained 👍</p>

62 <h3>Problem 3</h3>

63 <p>Find the area of a circle whose radius is 831 meters.</p>

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

65 <p>The area of the circle = 2,168,890.86 m²</p>

66 <h3>Explanation</h3>

67 <p>The area of a circle = πr²</p>

68 <p>Here, r = 831</p>

69 <p>Therefore, the area of the circle = π × 831² = 3.14 × 831 × 831 = 2,168,890.86 m².</p>

71 <h3>Problem 4</h3>

72 <p>The area of the square is 690,561 cm². Find the perimeter of the square.</p>

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

74 <p>The perimeter of the square is 3,324 cm.</p>

75 <h3>Explanation</h3>

76 <p>The area of the square = a²</p>

77 <p>Here, the area is 690,561 cm²</p>

78 <p>The length of the side is √690,561 = 831.</p>

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

80 <p>Here, a = 831</p>

81 <p>Therefore, the perimeter = 4 × 831 = 3,324.</p>

82 <p>Well explained 👍</p>

83 <h3>Problem 5</h3>

84 <p>Find the square of 832.</p>

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

86 <p>The square of 832 is 692,224.</p>

87 <h3>Explanation</h3>

88 <p>The square of 832 is found by multiplying 832 by 832.</p>
