Question

I didn’t understand the question but what’s the answer?

Answer 1

The length of the shadow of the object on the building when the object is 6 meters away from the wall is 2.4 meters.

To solve this problem, we can use similar triangles. Let the length of the shadow of the object on the building be x meters. We have two similar triangles:

The first triangle has sides of length 4 meters, 9 meters, and x meters. The second triangle has sides of length 6 meters, 9 meters, and x+3 meters.

We can set up the following proportion:

`(4)/(9) = (x)/(x+3)`

Multiplying both sides of the equation by x+3, we get:

4x+12 = 9x

Subtracting 4x from both sides of the equation, we get:

12 = 5x

Dividing both sides of the equation by 5, we get:

x =
`(12)/(5) = 2.4`

Therefore, the length of the shadow of the object on the building when the object is 6 meters away from the wall is 2.4 meters.
