let their sides be a and b respectively
then, their areas are (a2)m2 and (b2) m2 respectively
and,their perimeter are 4a and 4b respectively
therefore, 4a-4b=32
=>a-b=8____(1)
now, difference of their areas=208m2
therefore, a2-b2=208__-(using 1)
=>64+16b=208
=>16b=208-64
=>b=144/16
=>b=9
therefore, a=8+b=17
sides are 17 units and 9 units
