Answer:
they have the same area
Step-by-step explanation:
they have the same measure in legs and the same length hypotenuse. One of them is just transformed either by rotation or refection or translation 
 
        
             
        
        
        
4 1/3 
Okay, I know fractions are scary, but we can do this alright?
First, you see the whole number on the side? Get that first.
10- 5 = 5
now we have 5 left and a scary fraction.  Don't panic, let's do this.  We know 1 is 3/3.  1 can be anything as long as the number on top and the number at the bottom are the same then it would be one.
So 3/3 is one then we can subtract:
3/3 -2/3 .
We subtract the top number and leave the one at the bottom the same.
3-2 = 1
Then we have 1/3.
As you took one away from the 5, it becomes a 4 and you put back the left over, 1/3.
Then you answer will be :
4  1/3
        
             
        
        
        
He/she really tripping but maybe try simplifying them ?
        
             
        
        
        
9 x 9 = 81 
81 - 21 = 60 
60 / -6 
10
