The width of scale drawing is 4 inches

Step-by-step explanation:

The length of room =L1= 18 ft

The width of room =W1= 12 ft

The scale drawing length=L2 = 6 inches

The scale drawing width W2= x

According to rule of three

$\frac{L1}{L2} = \frac{W1}{W2}$

putting values in equation we get

$\frac{18}{6} = \frac{12}{x}$

$3=\frac{12}{x}$

Re-arranging the equation we get

$x=\frac{12}{3} \\x= 4$

So the width of scale drawing is 4 inches
