Problem 3 Easy

What is the perimeter of the following figure?

  • A.

    120

  • B.

    150

  • C.

    160

  • D.

    240

  • E.

    320

Answer:C

 

Starting from point A and walking clockwise around the figure, we mark the direction of movement and find that:

The sum of upward paths = the sum of downward paths = (15 +25) = 40m

The sum of rightward paths = the sum of leftward paths = 40m

Therefore, the perimeter of the figure is: (40 + 40) \times 2 = 160m.

Thus, the final answer is \boxed{160}m.
