nadya68 [22]

Answer:

The length of the shadow the telephone booth is <u>12 ft</u>.

Step-by-step explanation:

Given:

An adult elephant that is 10 ft tall casts a shadow that is 15 ft long.

The length of the telephone booth is 8 ft.

Now, to find the length of the shadow the telephone booth casts.

Let the length of the shadow the telephone booth be x.

As given, an adult elephant that is 10 ft tall casts a shadow that is 15 ft long.

So, 10 ft is equivalent to 15 ft.

Thus, 8 ft is equivalent to x.

Now, to get the length of the shadow of the booth we get cross multiplication method:

\frac{10}{15} =\frac{8}{x}

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

10x=120

<em>Dividing both sides by 10 we get:</em>

x=12.

Therefore, the length of the shadow the telephone booth is 12 ft.
