A car can travel for a distance of 350 miles in = 20 gallons The car can travel for a distance of 1 mile in = (20/350) gallons = 2/35 gallons Then The same car can travel for a distance of 875 miles in = (2/35) * 875 gallons = 1750/35 gallons = 50 gallons So it can be seen that 50 gallons of gasoline is required to travel for a distance of 875 miles. I hope the procedure is clear enough for you to understand.
4cm•2=8cm which is the length of the red paper so therefore Red paper= 4cmx8cm. Then your going to take 3cm-4cm= 1cm Next your going to solve for 7cm-8cm=1cm Which leaves you with an answer of 1cmx1cm more of visible red paper.
