Answer:

14 inches

Explanation:

Given that :

Scale drawing ; 7 inches = 3 feets ;

This means that 7 inches on the drawing equals 3 feets in real life

With this, we can calculate the length of scale drawing for 1 feet long object.

7 inches = 3 feets

x = 1 feet

Cross multiply :

3x = 7

x = 7/3 inches

Therefore, for a 6 feet long rug in real life, the length of drawing will be :

1 Feet = 7/3 inches

6 feets = (7/3 * 6) inches

(7/3 * 6) = 42 / 3 = 14 inches
