A rectangle has twice the area of a square. The length of the rectangle is 14 cm greater than that side of the square whereas breadth is equal to side of the square. Find the perimeter of the square?
Choose the correct choice from the following choices
A) 34  B) 38  C) 56  D) 28  E) 19
Let side of square be x.   Then for rectangle length = 14 + x and breadth = x.   It is given   Area of rectangle = 2 × (area of square)   length × breadth = 2(x × x)   (x + 14) × x = 2 × x2   x2 + 14x = 2x2   x2 = 14x   x = 14.   Perimeter of square = 4 × x = 56   Answer: 56
