Step-by-step explanation:

It already gives you all the info needed. Add all of the numbers. AB+DE=3

BC+DC=2 1/2

2 1/2+3 = 5 1/2

Answer 2

Answer:

Step-by-step explanation:

Perimeter =  AB + BC + CD + DE + EA

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

Perimeter = $1\frac{3}{4}$ +  $1\frac{3}{10}$ + $1\frac{1}{4}$ + $1\frac{1}{5}$

Perimeter = $\frac{35}{20} + \frac{26}{20} +\frac{25}{20} +\frac{24}{20} = \frac{110}{20}= \frac{11}{2}$

Perimeter = 5½ cm
