Question

on a scale drawing which of the following has a scale of 1:82cm represents 16m 1 inch represents 16 inches 1 cm represents 8cm inch represents 8 ft

Answer 1

In a scale drawing , we have two units .

One unit is in metre and other one is in centimetre.

We have to determine the ratio of ,

$1\colon8.$

in the scale drawing.

From the option given,

It is given that 2 cm represents 16m.

Therefore by unitary method we can say that,

If 2 cm is equal to 16m.

Then 1 cm is equal to 8m.

Hence , the ratio obatined is ,

$1\colon8.$

While in other options , the units are same which is not correct according to scale drawing.

Therefore, the correct answer is,

2cm represents 16m .
