Answer:
I think they are asking the area of the triangle so we are going with that.
Step-by-step explanation:
Easiest way to do this is find the area of the incomplete square, and then cut that in half for the triangle. 
so it is 4 cm wide
and 8 cm tall
length x width = area 
8 x 4 = 32
32/2 = 16
So your answer should be 16 cm
 
        
             
        
        
        
(1,10)(-3,2)
slope = (2-10) / (-3-1) = -8/-4 = 2
y = mx + b
slope(m) = 2
(1,10)...x = 1 and y = 10
now we sub and solve for b, the y int
10 = 2(1) + b
10 = 2 + b
10 - 2 = b
8 = b
equation is : y = 2x + 8.....or 2x - y = -8
        
             
        
        
        
251, 251, 252, 369, 671, 972 would be the answer
