Answer 1

35*25-20*30
=875-600
=275cmsquare

Answer 2

Answer: area of the full paper

Is equals to 35 into 25 which is equal to 875

Then after the stripes arebeen cut

Dimensions are 25 and 15 CM this is because is strip of 5m with cut all around the paper so the length and the breadth will be minimised by 10 cm so the area of the paper lift is equals to 25 into 15 which is equals to 375so now the area left is 875 - 375 which is equals to 500 so 500 is the area of the stripes
