Question

In the figure to the right, AE+DC= 1 1/5 m, AB=1 3/4 cm, DE=1 1/4 cm, and BC =1 3/10 cm. Find the perimeter of the figure.

Answer 1

9514 1404 393

Answer:

5 1/2 cm

Explanation:

The perimeter is the sum of the given lengths (in cm):

P = (1 1/5) +(1 3/4) +(1 1/4) +(1 3/10)

= (1 + 1 + 1 + 1) +(2/10 + 3/4 + 1/4 +3/10)

= 4 + 1 5/10

= 5 1/2

The perimeter of the figure is 5 1/2 cm.
