Question

A pole 3 m high has a shadow 5 m long when the shadow of a nearby building is 110 m long. How tall is the building?

Answer 1

Answer:

C. $\frac{x}{3}=\frac{110}{5}$

Step-by-step explanation:

Let x be the original height of building.

We have been given that a 3 meter pole has a shadow 5 m long. The shadow of a nearby building is 110 m long.

To find the original height of building we will use proportions as proportion states that two fractions are equal.

So we can set a proportion using our given information.

$\frac{\text{Actual height of building}}{\text{Actual height of pole}}=\frac{\text{Shadow of building}}{\text{Shadow of pole}}$

Upon substituting our given values in above equation we will get,

$\frac{x}{3}=\frac{110}{5}$

Therefore, the equation $\frac{x}{3}=\frac{110}{5}$ could be used to find the actual height of building.
