A grid is shown with a rectangle drawn on it. The rectangle is 10 inches long and 2 inches wide, labeled with 10 and 2 respectively.
Scale factor: 1 box= 6 inches
Maisie needs to convert this scale drawing from a scale factor of 1 box= 12 inches . The length in the scale drawing shown is 10 boxes. What will be the length of the boxes in the new drawing?
A. 12
B. 20
C. 5
D. 1
To convert the scale drawing from a scale factor of 1 box = 6 inches to a scale factor of 1 box = 12 inches, we need to double the length of each box in the scale drawing. Since the length in the scale drawing is 10 boxes, the new length will be 10 x 2 = <<10*2=20>>20 inches.
Therefore, the length of the boxes in the new drawing will be 20 inches.
The correct answer is B. 20.
