41 <h3>Problem 1</h3>

42 <p>A square garden has an area of 755,161 square meters. What is the length of one side of the garden?</p>

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

44 <p>The area of a square = a²</p>

45 <p>So, the area of the square = 755,161 m²</p>

46 <p>So, the length = √755,161 = 869.</p>

47 <p>The length of each side = 869 m.</p>

48 <h3>Explanation</h3>

49 <p>The length of the square garden is 869 meters.</p>

50 <p>Because the area is 755,161 m², the length is √755,161 = 869.</p>

51 <p>Well explained 👍</p>

52 <h3>Problem 2</h3>

53 <p>Sarah is designing a square piece of artwork with a side length of 869 millimeters. If the cost to frame per square millimeter is 2 cents, how much will it cost to frame the entire artwork?</p>

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

55 <p>The length of the artwork = 869 mm</p>

56 <p>The cost to frame 1 square millimeter of artwork = 2 cents.</p>

57 <p>To find the total cost to frame, we find the area of the artwork,</p>

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

59 <p>Here a = 869</p>

60 <p>Therefore, the area of the artwork = 869² = 869 × 869 = 755,161.</p>

61 <p>The cost to frame the artwork = 755,161 × 0.02 = 15,103.22 cents.</p>

62 <p>The total cost = 15,103.22 cents or $151.03.</p>

63 <h3>Explanation</h3>

64 <p>To find the cost to frame the artwork, we multiply the area of the artwork by the cost to frame per square millimeter. So, the total cost is $151.03.</p>

65 <p>Well explained 👍</p>

66 <h3>Problem 3</h3>

67 <p>Find the area of a circle whose radius is 869 meters.</p>

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

69 <p>The area of the circle = 2,373,532.78 m²</p>

70 <h3>Explanation</h3>

71 <p>The area of a circle = πr²</p>

72 <p>Here, r = 869</p>

73 <p>Therefore, the area of the circle = π × 869² = 3.14 × 869 × 869 = 2,373,532.78 m².</p>

74 <p>Well explained 👍</p>

75 <h3>Problem 4</h3>

76 <p>A square plot has an area of 755,161 square feet. Find the perimeter of the plot.</p>

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

78 <p>The perimeter of the plot is 3,476 feet.</p>

79 <h3>Explanation</h3>

80 <p>The area of the square = a²</p>

81 <p>Here, the area is 755,161 ft²</p>

82 <p>The length of the side is √755,161 = 869</p>

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

84 <p>Here, a = 869</p>

85 <p>Therefore, the perimeter = 4 × 869 = 3,476.</p>

86 <p>Well explained 👍</p>

87 <h3>Problem 5</h3>

88 <p>Find the square of 870.</p>

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

90 <p>The square of 870 is 756,900.</p>

91 <h3>Explanation</h3>

92 <p>The square of 870 is multiplying 870 by 870.</p>

93 <p>So, the square = 870 × 870 = 756,900.</p>

94 <p>Well explained 👍</p>
