31 <h3>Problem 1</h3>

32 <p>Find the length of the square, where the area of the square is 19,321 cm².</p>

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

34 <p>The area of a square = a² So, the area of a square = 19,321 cm² So, the length = √19,321 = 139. The length of each side = 139 cm</p>

35 <h3>Explanation</h3>

36 <p>The length of a square is 139 cm. Because the area is 19,321 cm² the length is √19,321 = 139.</p>

37 <p>Well explained 👍</p>

38 <h3>Problem 2</h3>

39 <p>Anna is planning to tile her square kitchen floor of length 139 feet. The cost to tile a foot is 5 dollars. Then how much will it cost to tile the full floor?</p>

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

41 <p>The length of the floor = 139 feet The cost to tile 1 square foot of floor = 5 dollars. To find the total cost to tile, we find the area of the floor, Area of the floor = area of the square = a² Here a = 139 Therefore, the area of the floor = 139² = 139 × 139 = 19,321. The cost to tile the floor = 19,321 × 5 = 96,605. The total cost = 96,605 dollars</p>

42 <h3>Explanation</h3>

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

44 <p>So, the total cost is 96,605 dollars.</p>

45 <p>Well explained 👍</p>

46 <h3>Problem 3</h3>

47 <p>Find the area of a circle whose radius is 139 meters.</p>

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

49 <p>The area of the circle = 60,752.26 m²</p>

50 <h3>Explanation</h3>

51 <p>The area of a circle = πr²</p>

52 <p>Here, r = 139</p>

53 <p>Therefore, the area of the circle = π × 139²</p>

54 <p>= 3.14 × 139 × 139</p>

55 <p>= 60,752.26 m².</p>

61 <h3>Explanation</h3>

62 <p>The area of the square = a²</p>

63 <p>Here, the area is 19,321 cm²</p>

64 <p>The length of the side is √19,321 = 139</p>

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

66 <p>Here, a = 139</p>

67 <p>Therefore, the perimeter = 4 × 139 = 556.</p>

68 <p>Well explained 👍</p>
