70 <h3>Problem 3</h3>

71 <p>The area of a rectangle is 129 square units. If the length is 43 units, then what is the measure of its width?</p>

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

73 <p>Area of rectangle: 129 sq units</p>

74 <p>Factors of 129: 1,3,43,129</p>

75 <p>We know that the area of a rectangle is the product of its length and breadth.</p>

76 <p>Given, length= 43 units</p>

77 <p>There exists a factor pair of 129, which is (3,43). Hence, width is 3 units. Let’s check it through the formula for area.</p>

78 <p>So, length×width = area</p>

79 <p>⇒ 43 × width = 129</p>

80 <p>⇒ width = 129/43 = 3</p>

104 <h2>FAQs on Factors of 129</h2>

105 <h3>1.What can you multiply to get 129?</h3>

106 <p> We can multiply some integers with some other integers to get the product as 129. Those particular integers are:</p>

107 <p>1,3,43 and 129, out of which we make factor pairs for multiplication purposes. The factor pairs are: (1,129), (3,43).</p>

108 <p>129×1=129 and 3×43=129 </p>

109 <h3>2.What perfect square goes into 129?</h3>

110 <p>√129 = √(3×43). We can see from this that 129 cannot be a<a>perfect square</a>, since its prime factors cannot be taken out as pairs. The approximate value of the<a>square root</a>of 129 is ±11.36. </p>

111 <h3>3.What can 129 be divided by?</h3>

112 <p>Perfect division of 129 can be possible, only when 129 is divided by 1,3,43,129, leaving no<a>remainder</a>. These are also called the factors of 129. </p>

113 <h3>4.What is the factor tree of 129?</h3>

114 <p>The number 129 is written on top and two branches are extended. Fill in those branches with a factor pair of the number above, i.e., 129.</p>

115 <p>Continue this process until each branch ends with a prime factor (number). The first two branches of the factor tree of 129 are 3 and 43. </p>

116 <h3>5. Is 129 a perfect cube?</h3>

117 <p>∛129 = ∛(3×43). </p>

118 <p>We can see from this that 129 cannot be a<a>perfect cube</a>, as its prime factors are not grouped to the<a>power</a>of three. The approximate value of the<a>cube root</a>of 129 is 5.05277.... </p>
