Answer 3

first calculate the area of the shaded rectangle

4 units * 8 units = ?

Answer 4

32 @Vocaloid

Answer 5

good, now divide

area of real rectangle/area of drawing = 288/32 = 9

now, since we're dealing with area, we take the square root of that to get the scale factor

so the scale factor is sqrt(9) = 3
