Question

7. On a scale drawing of a planned office space, one inch represents 6 feet.

How wide is the conference room if the width in the drawing is 3 inches?

Answer 1

The width of the conference room = 18 feet

Explanation:

Given:

Scale drawing of a planned office space is represented as

1 in : 6 feet

To find the width of the conference room if the width in the drawing is 3 inches.

Solution:

Scale is the representation of ratio of lengths in the drawing to the actual length.

The scale given here means that 1 inch length in the drawing corresponds to 6 feet length actually.

Thus, in order to find the actual length of 3 inches, we can use unitary method

If 1 inch in drawing corresponds to = 6 feet

∴ 3 inches in drawing corresponds to =
`3* 6 \ft` = 18 feet

Thus, width of the conference room = 18 feet
