Question

In a scaled drawing, 1 millimeter represents meters. How many square millimeters on the drawing represent 1 square meter?
A. 1/22,500
B. 150/22,500
C. 120
D. 22,500

Answer 1

missing information, but from the appearance of the digits 225 in the answers, I will
conclude that 1 mm represents 15 metres.

15 m ----> 1 mm
15^2 m^2 ----> 1 mm^2
225 m^2 ----> 1 mm^2
1 m^2 = 1/225 mm^2

Don't see that, so my assumption was off, or else the question is off.
You decide what the given ratio was, then fix it accordingly

Answer 2

sorry it was 150

Answer 3

so did you make the necessary changes to my reply ?

Answer 4

1mm = 150m
(1/150)mm = 1m.
(1/150)^2mm^2 = 1m^2
(1/22,500)mm^2 = 1m^2.
