41 <h3>Problem 1</h3>

42 <p>Find the length of the square, where the area of the square is 429,025 cm².</p>

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

44 <p>The area of a square = a²</p>

45 <p>So, the area of a square = 429,025 cm²</p>

46 <p>So, the length = √429,025 = 655.</p>

47 <p>The length of each side = 655 cm</p>

48 <h3>Explanation</h3>

49 <p>The length of a square is 655 cm.</p>

50 <p>Because the area is 429,025 cm² the length is √429,025 = 655.</p>

51 <p>Well explained 👍</p>

52 <h3>Problem 2</h3>

53 <p>Emily is planning to paint her square garden fence of length 655 feet. The cost to paint a foot is 1.5 dollars. Then how much will it cost to paint the full fence?</p>

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

55 <p>The length of the fence = 655 feet</p>

56 <p>The cost to paint 1 square foot of the fence = 1.5 dollars.</p>

57 <p>To find the total cost to paint, we find the area of the fence,</p>

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

59 <p>Here a = 655</p>

60 <p>Therefore, the area of the fence = 655² = 655 × 655 = 429,025.</p>

61 <p>The cost to paint the fence = 429,025 × 1.5 = 643,537.5.</p>

62 <p>The total cost = 643,537.5 dollars</p>

63 <h3>Explanation</h3>

64 <p>To find the cost to paint the fence, we multiply the area of the fence by the cost to paint per foot. So, the total cost is 643,537.5 dollars.</p>

66 <h3>Problem 3</h3>

67 <p>Find the area of a circle whose radius is 655 meters.</p>

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

69 <p>The area of the circle = 1,349,533.5 m²</p>

70 <h3>Explanation</h3>

71 <p>The area of a circle = πr²</p>

72 <p>Here, r = 655</p>

73 <p>Therefore, the area of the circle = π × 655² = 3.14 × 655 × 655 = 1,349,533.5 m².</p>

74 <p>Well explained 👍</p>

75 <h3>Problem 4</h3>

76 <p>The area of the square is 429,025 cm². Find the perimeter of the square.</p>

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

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

79 <h3>Explanation</h3>

80 <p>The area of the square = a²</p>

81 <p>Here, the area is 429,025 cm²</p>

82 <p>The length of the side is √429,025 = 655</p>

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

84 <p>Here, a = 655</p>

85 <p>Therefore, the perimeter = 4 × 655 = 2,620.</p>

86 <p>Well explained 👍</p>

87 <h3>Problem 5</h3>

88 <p>Find the square of 656.</p>

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

90 <p>The square of 656 is 430,336</p>

91 <h3>Explanation</h3>

92 <p>The square of 656 is multiplying 656 by 656.</p>

93 <p>So, the square = 656 × 656 = 430,336</p>
