We use the vertical side as the base: it is a vertical segment, so it's length is the difference of the y coordinates of its endpoints:
The height would be the segment starting from 
, perpendicular to the base. Since this is a horizontal segment, its length is the difference of the x coordinates of its endpoints:
So, the area is given by
Ik the first equation you just distribute three to north numbers and it’ll give you 9x+15 and in the second one you can distribute a negative 1 and it’ll give you 9x+15
√53 = 7.28
Therefore, it lies between 7 and 8.
Answer:
