You would need four busses
        
             
        
        
        
First use Pythagoras theorem to find the remaining length of the base.
Then multiply the base with the altitude and divide that by 2 and you'll get the area
        
             
        
        
        
A. albatross - blue jay = 3 1/2 - 39/100
================== (3*2)+1/2 - 39/100
================== 7/2 - 39/100
================== 311/100
================== 3.11
b. Golden eagle - seagull = 2 1/4 - 11/5
======================= (2*4)+1/4 - 11/5
======================= 9/4 - 11/5
