Answer:
I am not sure .but i will try
i think so i will give correct answer
perpendicular of triangle is 22-10 cm =12 cm bcz both sides of triangle are equal =22
area of rectangle l×w= 22×17=374
area of triangle =h×b/2 Now we r not having h
lets find it
use pythagorus theorum (h2=P2+b2....2 here is square)
h=22.5cm
22.5×19=427(area of triangle )
374+427=801cm sq
i tried my best dont know its righr of wrong
pls mark me as brainlieast
