Answer:The lateral area is 
Step-by-step explanation:
we know that
The lateral area of the right prism is equal to
where
P is the perimeter of the base
H is the height of the prism
Find the perimeter of the base P
----> the rhombus has four equal sides
substitute
I will get you started.
x^2+4x-4 = 8
x^2 + 4x - 4 - 8 = 0
x^2 + 4x - 12 = 0
You must now use the quadratic formula.
In the formula, a = 1, b = 4, and c = -12.
Take it from here.
