Answer 1

Answer:

The mural in David's drawing is 4 cm long.

Step-by-step explanation:

Given:

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.

Now, to find how long is the mural in David's drawing.

Let the length of mural in David's drawing be $x\ cm$.

So, as given 1 cm = 4 ft.

1 cm is equivalent to 4 ft.

Thus, $x\ cm$ is equivalent to 16 feet.

Now, to get the length of mural in David's drawing by using the cross multiplication method:

$\frac{1}{4} =\frac{x}{16}$

By cross multiplication:

$16=4x$

Dividing both sides by 4 we get:

$4=x$

$x=4\ cm.$

Therefore, the mural in David's drawing is 4 cm long.
