A carpenter had a board which measured 3m × 2m. She cut out a rectangular piece of 250cm × 90cm. What is the ratio of the area of cut out piece and the remaining piece?


Area of board = length× breadth


= 3× 2 = 6 m2


She cut rectangular piece = 250cm× 90cm


Area of rectangular piece = 250× 90 = 22500 cm2



Area of rectangular piece =


Remaining area of board = 6 – 2.25 = 3.75 m2
