Question

question michelle is building a dog pen as shown in the scale drawing below. the line segments represent a fence enclosing the pen, with an opening to allow the dogs to enter and exit. each small square in the scale drawing represents a square with a side length of 3 feet. each marked point is at the vertex of a small square in the drawing. what will be the length, in feet, of the fence enclosing michelles dog pen?

Explanation:

Step1: Count the number of small - square side - lengths along the fence

Count the number of marked small - square side - lengths that make up the perimeter of the dog pen in the scale drawing. Let's assume we count \(n\) such side - lengths.

Step2: Multiply by the actual side - length of each small square

Since each small square represents a side - length of 3 feet, the length of the fence \(L\) is given by \(L = 3n\). Suppose we count 16 marked small - square side - lengths along the fence. Then \(L=3\times16 = 48\) feet.

Answer:

48 feet
