Answer:

The actual length of the helicopter is <u>23 feet</u>.

Step-by-step explanation:

Given:

On a scale drawing, a helicopter is 2.3 feet long.

The scale on the drawing shows a ratio of 1 foot to 10 feet.

Now, to find the actual length of the helicopter.

Let the actual length of helicopter be x.

On scale drawing length of helicopter = 2.3 feet.

The scale on the drawing shows a ratio = 1:10.

Now, as ratios are given so by setting proportion we solve it:

\frac{2.3}{x} =\frac{1}{10}

<em>By cross multiplying we get:</em>

⇒ 2.3\times 10=x

⇒ 23=x

⇒ x=23\ feet.

Therefore, the actual length of the helicopter is 23 feet.
