It very much depends on what z is.
Assuming that the 40 and 30 refer to sides of a rectangle and not to any of the infinite number of other possible shapes, the answer is 50.
Write two simultaneous equations and solve them. One for the perimeter, one for the area.
One rectangle that has a perimeter of 30 has a length of 5 and a width of 10.

The measurement of 30 minutes is a measurement of time.
One rectangle that has a perimeter of 30 has a length of 5 and a width of 10.
you multiply it together so it is 28,080(your measurement here)^3
The diagonal of a rectangle with the length of 30 yd and the width of 30 yd is approximately 42.43 yd
