Answer 2

Scale used for drawing is 1 cm = 1.75 m

Explanation:

An architect makes a scale drawing of a house.

Actual width of porch = 7 meters

Width of porch on drawing = 4 cm

So, Actual width = Drawing width

So, 4 cm = 7 m

`1 cm = (7)/(4) m`

1 cm = 1.75 m

So, Scale: 1 cm = 1.75 m

So, Option B is correct

B)1 cm = 1.75 m

Hence scale used for drawing is 1 cm = 1.75 m
