</span><span>dimensions </span>copy of a painting--------------> 1.75 in x 5.25 in
for 1.75 in
[original painting]=[copy of a painting]/[scale]
[original painting]=[1.75]/[(0.5/12)]=42 cm
for 5.25 in
[original painting]=[copy of a painting]/[scale]
[original painting]=[5.25]/[(0.5/12)]=126 cm
the answer Part A) is
