perimeter of a rectangle = 2 (length + breadth) or, 56 = 2(2.5 breadth + breadth) or, 56 = 7 breadth breadth = 56 7 = 8 cm length = 2.5*8 = 20 cm
The dimensions of the rectangle are 8 cm in width and 20 cm in length. The width was found to be 8 cm, and by using the relation between length and width, the length was calculated to be 20 cm. Together, these dimensions satisfy the stated perimeter of 56 cm.
