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
