To find: The height of the dog house.

Answer to Problem 53CR
The height of the dog house is
Explanation of Solution
Given information:
The height of Person M’s house is 9 meters and its shadow is 1.5 meters long. The shadow of a doghouse is 0.2 meter long.
Calculation:
The height of Person Mhouse and its shadow makes a right triangle. Also, the height of the doghouse and its shadow make a right angle triangle. The two triangles are similar. By similarity of triangles, their side lengths are proportional.
Let height of thedog house be
Therefore, the height of the dog house is
