Answer:
Their were 42 kids on each bus.
Step-by-step explanation:
You have to divide the number of kids(210) by the number of buses. 
 
        
                    
             
        
        
        
triangle on right is the same as the triangle on the left
use pythagorean theorem
hypotenuse will give to the sides of the rectangle 
a^2 + b^2 = hypotenuse squared 
10.4^2 = 108.16
15.3^2 = 234.09
342.25 = hypotenuse squared
take the square root in both sides
hypotenuse = the square root of 342.25 = 
18.5
add up the areas of the 2 triangles and rectangle 
triangle area is 1/2 times 10.4 times 15.3 =
79.56
2 triangles areas are 159.12
rectangle area is 18.5 × 7 = 129.5
159.12 + 129.5 = 288.62
answer 1 = 288.62
second question:
to get 1 side take the 
square root of 702.25 which is
26.5
to get the perimeter 
multiply 26.5 by 4 which is
106
answer 2 is choice B 106
