I have this assignment at school to do with Areas and Perimeters. This is the final question, and I am totally stuck.
b) Find x if the total area is to be 1000m2
c) find the cost of the outer border given that materials cost $12.75 per metre.

Is anyone able to help me?
Oh yes, if it helps, this is the expression:
A = x2 (1 + PI/2) m2
