(a) The scale of the drawing is in centimeters.
(b) The scale factor of the drawing is 5 mm.
(c) The size of the spider's mate drawing should be 4 cm.
Given scale drawing of a spider is 5 cm long.
The actual spider is 10 mm long
(a) The scale of the drawing is in centimeters because the scale drawing of a spider given is in 5 centimeters,
(b) Scale factor:
The scale factor shows by how much the original model has been multiplied or divided by to get the measurements of the drawing.
In this case, the spider is 10 mm long but the drawing length is 5 cm.
Let’s convert both into the same units
5 cm - 50 mm
Original - 10 mm
Painting -50 mm
X - scale factor
50 = X * 10
X = 50/10 = 5 mm
The spider has been multiplied/ enlarged by a scale factor of 5 mm to draw the painting.
(c) Given the spider's mate is 8mm long.
Now for the drawing, we need to choose the scale factor as above to get the perfect measurement.
So, the 8 mm spider has been enlarged by a scale factor of 5 mm to get the size for drawing.
= 8 * 5
= 40 mm
= 4 cm
The size of the drawing should be 4 cm.
