Perimeter is straightforward:
P = 18 + 6 + 11 + 9 = 44m
To calculate the area of an irregular quadrilateral you need the side lengths and the diagonal lengths. Since the diagonal lengths are not provided I'll give the formula.
For:
a, b, c and d are lengths of sides
s is the semiperimeter, s = (a + b + c + d)/2
p and q are the diagonals
A = SQR[(s - a)(s - b)(s - c)(s - d) - 1/4(ac + bd + pq)(ac + bd - pq)]
