The sides of a rectangle are in the ratio of 6 : 5 and its area is 1331 sq.m. Find the perimeter of rectangle.	Pick one
A) 121	B) 123	C) 125	D) 122	E) 126
Let 6x and 5x be sides of the rectangle   6x × 5x = 1331   11xpower2 = 1331   xpower2 = 1331/11=

121=&gt; x = 11   Length = 6x = 6 × 11 = 66   Breadth = 5x =&gt; 5 × 11 = 55   Perimeter = 2 (l+b) =&gt; 2 (66+55) = 121 m   121nswer is 121.
