Fishing: fishing rod is 4$. Rectangle: perimeter is $9$. Square: ${c}^{2}$Explanation: Fishing: $2 x$+8$#

$2 x + 8 = 0$

$2 x = - 8$

$x = \frac{- 8}{2}$

$x = - 4$

reject the $-$ sign

Rectangle: $2 x - 3 c m$

$2 x - 3 = 0$

$2 x = 3$

$x = \frac{3}{2}$ or $1 \frac{1}{2}$

$P = 2 L + 2 W$

$P = 2 \left(3\right) + 2 \left(1 \frac{1}{2}\right)$

$P = 6 + 3$

$P = 9$

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 ${c}^{2}$.
