Answer 1

 the answer is C if the scale is 1cm:4m 4x6 is 24

Answer 2

Answer: Option 'C' is correct.

Explanation:

Since we have given that

Length of a fence on a scale drawing = 6 cm

Scale = 1 cm : 4 m

Let the actual length of the fence be x

Since there is direct variation between the scale and actual.

According to ratio, we will have,

`(1)/(4)=(6)/(x)\\\\x=6* 4\\\\x=24\ m`

Hence, Option 'C' is correct.
