Question

The figure below represents a building in the shape of a pentagon. Using the scale 1 inch = 94 feet, what is

the perimeter of the building?

Answer 1

If 1 inch = 94 feet, 4 inches is 94 × 4.

94 × 4 = 376

Add 376 to itself 5 times, or use a simpler method and multiply 376 by 5.

376 + 376 + 376 + 376 + 376 = 1,880

376 × 5 = 1,880

Answer:

The perimeter is 1,880 feet. (20 without the scale applied)
