Might fail math, need desperate understandinf these problems

the area of a rectangular parking lot can represented by
a=4x + 200x

what is the expression for the length and width of the parking lot

find an expression for the perimeter of the parking lot

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)
