Fishing: fishing rod is #4$#.

Rectangle: perimeter is #9#.

Square: #c^2#

Fishing: #2x# +#8$#

#2x+8=0#

#2x=-8#

#x=(-8)/2#

#x=-4#

reject the #-# sign

Rectangle: #2x-3cm#

#2x-3=0#

#2x=3#

#x=3/2# or #1(1)/(2)#

#P=2L+2W#

#P=2(3)+2(1(1)/(2))#

#P=6+3#

#P=9#

Square:

Area of the square is #s^2#, where #s# is the sides. Since it says that the side is #c# centimeters, area is now equal to #c^2#.
