Perimeter = 4 x sides
48 = 4 (x + 3)
48 = 4x + 12
36 = 4x
x = 9

Check:
x + 3 = 9 + 3 = 12
12 x 4 = 48

ΔBED and Δ DEC are similar (AAA). Therefore we have the proportion:

$\dfrac{a}{18}=\dfrac{4}{a}$ cross multiply

$a^2=(18)(4)\\\\a^2=72\to a=\sqrt{72}\\\\a=\sqrt{36\cdot2}\\\\a=\sqrt{36}\cdot\sqrt2\\\\\boxed{a=6\sqrt2}$
