Answer» Let the breadth to be x and the length to be y. Hence, perimeter becomes 5x. Now, 5x = 2(x+y).Or, 3x = 2y -----------1. Again, xy = 216.Or, x = 648/y ----------2. Putting the value of x in eq. no. 1, we get, 648/y = 2y.Or (2yy) = 648.Or y = Sqrt 324 = 18 cm.

Answer»

Let the breadth to be x and the length to be y.

Hence, perimeter becomes 5x.

Now, 5x = 2(x+y).Or, 3x = 2y -----------1.

Again, x*y = 216.Or, x = 648/y ----------2.

Putting the value of x in eq. no. 1, we get,

648/y = 2y.Or (2y*y) = 648.Or y = Sqrt 324 = 18 cm.
