For the smaller triangle ;
15^2 + b^2 = 17^2
b = 8
To check the work
15^2 + 8^2 = 289
17^2 = 289
(This is if the bottom number on the smaller triangle says 15, its a bit hard to read..)
        
             
        
        
        
using the given coordinates, the rectangle is 7 by 3 units
area = 7*3 = 21 square units
