Here is your answer -
Let the length of one perpendicular be a cm.
Then, the length of the other perpendicular =(a+6)cm
Now, area of triangle =36 sq.cm
⇒ 1/2×a×(a+6)=36
⇒a^2 +6a=72
⇒a^2 +6a−72=0
⇒a^2+12a−6a−72=0
⇒(a+12)(a−6)=0
⇒a=12 or a=6
But length cannot be negative, hence a=6 cm
Thus length of its perpendicular sides are, a=6 cm and a+6=12 cm.
