Question

In the figure to the right, AE + DC = 1 1/5 cm, 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:

Add up the given segment lengths.

Perimeter = AE +DE +DC +BC +AB

= (AE +DC) +DE +BC +AB

= 1 1/5 +1 1/4 +1 3/10 +1 3/4

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

= 2 5/10 + 3

= 5 1/2

The perimeter is 5 1/2 cm.
