Question

David made a scale drawing of a mural he is going to paint. He used a scale of 1 cm=4ft. If the actual mural will be 16 feet long, how long is the mural in David's drawing

Answer 1

Answer:

4 cm

Step-by-step explanation:

we know that

The scale drawing is

$\frac{1}{4}\ \frac{cm}{ft}$

That means ----> 1 cm in the drawing represent 4 ft in the mural

so

To find out the dimensions in the drawing, multiply the actual dimension by the scale drawing factor

so

$(16\ ft)(\frac{1}{4}\ \frac{cm}{ft})=4\ cm$
