I have seen some scales that convert units and some that don't
first is convert
the scale converts from smaller to bigger
?:1in
6ft/8in=0.75ft/1
scale is 0.75ft:1in
other one doesn't convert dimentions
6ft=6*12in=72in
72in:8in
9:1
that is most ilkely what teacher is looking for
scale is 9:1
72in:8in
Answer :-
Area of the rectangular painting = 6348 cm²
length = 92 cm
Area = length × width
6348 cm² = 92cm × width
=> 6348cm² / 92cm = width
=> width = 69 cm
Thus, the width of the rectangular painting is 69 cm
