the length of a rectangle exceeds its breadth by 9 cm. if the length and breadth are each increased by 3cm the area of the new rectangle will be 84 cm^{2} more than that of the given rectangle . calculate the length and breadth of the given rectangle

Let x = the breadth of the rectangle

x+ 9 = the length of the rectangle

âˆ´According to the question,

(x+9+3)(x+3) = x^{2} + 9x + 84

The length of the rectangle = 8cm.

The breadth of the rectangle = 8+ 9=17 cm.
