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.

Step-by-step explanation:

The perimeter of the shown figure is the sum of the lengths of all sides. So, the perimeter is

Using commutative and reflexive properties, rewrite it as follows:

Therefore, the perimeter is

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this
