46 <h3>Problem 1</h3>

47 <p>Find the length of the square, where the area of the square is 123456787654321 cm².</p>

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

49 <p>The area of a square = a² So, the area of a square = 123456787654321 cm² So, the length = √123456787654321 = 11111111. The length of each side = 11111111 cm</p>

50 <h3>Explanation</h3>

51 <p>The length of a square is 11111111 cm.</p>

52 <p>Because the area is 123456787654321 cm², the length is √123456787654321 = 11111111.</p>

53 <p>Well explained 👍</p>

54 <h3>Problem 2</h3>

55 <p>Sarah wants to cover her square garden of length 11111111 feet with tiles. If each tile costs 2 dollars, how much will it cost to cover the full garden?</p>

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

57 <p>The length of the garden = 11111111 feet The cost to cover 1 square foot of garden = 2 dollars. To find the total cost to cover, we find the area of the garden, Area of the garden = area of the square = a² Here a = 11111111 Therefore, the area of the garden = 11111111² = 123456787654321. The cost to cover the garden = 123456787654321 × 2 = 246913575308642. The total cost = 246913575308642 dollars</p>

58 <h3>Explanation</h3>

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

60 <p>So, the total cost is 246913575308642 dollars.</p>

62 <h3>Problem 3</h3>

63 <p>Find the area of a circle whose radius is 11111111 meters.</p>

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

65 <p>The area of the circle = 387850640124.5 m²</p>

66 <h3>Explanation</h3>

67 <p>The area of a circle = πr²</p>

68 <p>Here, r = 11111111</p>

69 <p>Therefore, the area of the circle = π × 11111111² = 3.14 × 11111111 × 11111111 = 387850640124.5 m².</p>

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

74 <p>The perimeter of the square is 44444444 cm.</p>

75 <h3>Explanation</h3>

76 <p>The area of the square = a²</p>

77 <p>Here, the area is 123456787654321 cm²</p>

78 <p>The length of the side is √123456787654321 = 11111111</p>

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

80 <p>Here, a = 11111111</p>

81 <p>Therefore, the perimeter = 4 × 11111111 = 44444444.</p>
