46 <h3>Problem 1</h3>

47 <p>Find the length of a square, where the area of the square is 667,489 cm².</p>

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

49 <p>The area of a square = a² So, the area of a square = 667,489 cm² So, the length = √667,489 = 817. The length of each side = 817 cm</p>

50 <h3>Explanation</h3>

51 <p>The length of a square is 817 cm because the area is 667,489 cm².</p>

52 <p>The length is √667,489 = 817.</p>

53 <p>Well explained 👍</p>

54 <h3>Problem 2</h3>

55 <p>Sarah is planning to tile her square courtyard of length 817 feet. The cost to tile a foot is 5 dollars. How much will it cost to tile the entire courtyard?</p>

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

57 <p>The length of the courtyard = 817 feet The cost to tile 1 square foot = 5 dollars. To find the total cost to tile, calculate the area of the courtyard, Area = a² Here a = 817 Therefore, the area = 817² = 817 × 817 = 667,489. The cost to tile the courtyard = 667,489 × 5 = 3,337,445. The total cost = 3,337,445 dollars</p>

58 <h3>Explanation</h3>

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

60 <p>The total cost is 3,337,445 dollars.</p>

61 <p>Well explained 👍</p>

62 <h3>Problem 3</h3>

63 <p>Find the area of a circle whose radius is 817 meters.</p>

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

65 <p>The area of the circle = 2,096,502.85 m²</p>

66 <h3>Explanation</h3>

67 <p>The area of a circle = πr²</p>

68 <p>Here, r = 817</p>

69 <p>Therefore, the area of the circle = π × 817² = 3.14 × 817 × 817 = 2,096,502.85 m².</p>

71 <h3>Problem 4</h3>

72 <p>The area of the square is 667,489 cm². Find the perimeter of the square.</p>

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

74 <p>The perimeter of the square is 3,268 cm.</p>

75 <h3>Explanation</h3>

76 <p>The area of the square = a²</p>

77 <p>Here, the area is 667,489 cm²</p>

78 <p>The length of the side is √667,489 = 817</p>

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

80 <p>Here, a = 817</p>

81 <p>Therefore, the perimeter = 4 × 817 = 3,268 cm.</p>

82 <p>Well explained 👍</p>
