(I'm sorry I don't understand this...can anyone help??..)

the complete question in the attached figure

we know that
[scale]=0.5/12
[scale]=[copy of a painting]/[original painting]

dimensions 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
the dimensions of the original painting are 42 cm x 126 cm

Part B)
Find the area of the original painting.
[area of the original painting]=42*126=5292 cm²

the answer Part B) is
area of the original painting is 5292 cm²

Part C)
One centimeter is equal to approximately 0.033 foot. Find the dimensions of the original painting in feet.

the dimensions of the original painting are 42 cm x 126 cm
then

for 42 cm
if 1 cm----------------> 0.033 ft
42 cm----------------> X
X=42*0.033=1.386 ---------> 1.386 ft

for 126 cm
if 1 cm----------------> 0.033 ft
126 cm----------------> X
X=126*0.033=4.158 --------> 4.158 ft

the answer Part C) is
the dimensions of the original painting in feet are 1.386 ft x 4.158 ft

Part D) Find the area of the painting in square feet. Round to the nearest thousands.

the dimensions of the original painting in feet are 1.386 ft x 4.158 ft
{Area original painting in feet]=1.386*4.158=5.763 ft²

the answer part C) is
the area original painting in feet is 5.763 ft²
