The ratio between the perimeter and the breadth of a rectangle is 5 : 1. If the area of the rectangle is 216 sq. cm, what is the length of the rectangle?  Pick one: A) 11 B) 18 C) 92 D) 27 E) 28
Explanation:   =&gt; 2l + 2b = 5b   =&gt; 3b = 2l   b=(2/3)l   Then, Area = 216 cm2   =&gt; l x b = 216   =&gt; l x (2/3)l =216   =&gt; l2 = 324   l = 18 cm.   Answer: 18) 18
