Respuesta :
The length and width of the scale drawing after reconsideration of the scale factor as 1/9 will be 5 and 4 inches respectively so option (C) will be correct.
What are the ratio and proportion?
The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b, will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Given that
At scale ratio; 1/3
Length = 15 inches , width = 12 inches
Original dimension will be = dimension/ scale ratio
Â
so,
Original length = 15(3) = 45 inches
Original width= 12(3) = 36 inches
At scale ratio; 1/9
Length = 45/9 = 5 inches
Width = 36/9 = 4 inches
Hence the correct answer to this question will be 5 inches long and 4 inches wide.
