Question

help plz (pic included)

Answer 1

Answer:

13.8

Step-by-step explanation:

perimeter = sum of all sides

in a parallelogram opposite sides are equal,

c=[60.8-(16.6)2]÷2

this gives

c=13.8

Answer 2

Answer:

13.8 m

a=16.6

b=16.6 parallel sides equal

c=d parallel sides equal

p = 16.6+16.6+c+c

60.8= 33.2+2 c

60.8-33.2=2c

27.6 = 2c

13.8 m
