Scale: 1 inch : 40cm a) 2 inches x 40 cm = 80 cm ; 1.5 inches x 40 cm = 60 cm b) Area = 80 cm * 60 cm = 4,800 cm² c) 80 cm * 1 inch / 2.54 cm = 31.50 inches ; 60 cm * 1 inch/2.54 cm = 23.60 inches d) Area = 31.50 in * 23.60 in = 743.40 inches²

Answer 2

ok so 1inch=40cm

2 inches by 1.5
multiply everybody by 40 and make them all centimeters
20*2=80
1.5*40=60

80cm by 60cm


1inch=2.54cm
find how many inches in 1 cm
divide both sides by 2.54
1/2.54inch=1cm

80 by 60 cm
multiply that by 1/2.54 nd find inches iquivlent

80 times 1/2.54=31.4960629921259842519685037008
60 times 1/2.54=23.622047...


ok so

dimentions is 31.4960629921259842519685037008 inches by 23.622047 inches
