56 <h3>Problem 2</h3>

57 <p>A rectangular garden has a width of 43 meters and the total area is 1161 square meters. Find the length?</p>

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

59 <p>27 meters.</p>

60 <h3>Explanation</h3>

61 <p>To find the length of the garden, we use the formula,</p>

62 <p>Area = length × width</p>

63 <p>1161 = length × 43</p>

64 <p>To find the value of length, we need to shift 43 to the left side.</p>

65 <p>1161/43 = length</p>

66 <p>Length = 27.</p>
