apologiabiology

ok so 1inch=40cm

2 inches by 1.5
multiply everybody by 40 and make them all centimeters
202=80
1.540=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
