Question

What is the distance across the river?

Answer 1

Answer:

The correct answer is,

d = 300 feet

Step-by-step explanation:

Points to remember

The ratio of of corresponding sides of similar triangles are equal.

From the figure we can see two similar triangles.

To find the value of d

It is given that, the ratio of d to 150 ft is the same as the ratio of 40 ft to 20 ft

d/150 = 40/20

d = (150 * 40)/20

d = 300

Therefore the value of d = 300 ft
