Because the left side is eclipsed in an absolute value, we have two possible values of x, denoted by:
2x+4 = 12 and -(2x+4) = 12
Solving for both of these, we are presented with the two values of x:
x = 4 and x = -8
Factoring the left side of the equation
x(2x-5) = 150
x = 10 so the dimension are 10 and (2(10) - 5 = 15
length = 15 feet , width = 10 feet.
