Dimensions of the cardboard=4 cm and 2 cm Area of the cardboard= 2 cm*4 cm=8 cm² Since the least dimension= 2 cm, the greatest possible circle can have a diameter of maximum 2 cm. Radius=D/2=1 cm. Area of the circle=πR² =22/7*1*1 cm² =22/7 cm² Remaining area=8 cm² - 22/7 cm² =34/7 cm² =4 6/7 cm²(Mixed fraction) Ans:The remaining area is 4 6/7 cm².
