Find the area of the rectangle with the perimeter of 206 cm and the difference between its length and breath is 23 cm.
Perimeter of the rectangle P = 2 * (L + B) = 206 cm => L + B = 103 cm.
The defference between length and breath D = L - B = 23 cm.
=> P + D = 2L = 126 => L = 63 cm.
=> B = 40 cm.
Area of the rectangle A = L * B = 63 * 40 = 2520 Sq. cm.
