y-0=3/8(x- -4)
y= 3/8x+ 3/2
3/2= y intersept
(0,3/2)= second point

The figure on the top left is a triangle with base 11 and height 8, for an area of

Immediately below, we have a rectangle with dimensions 11 and 9, for an area of

Moving to the right, we have a parallelogram with base 9 and heght 11, which again has height

Finally, the rightmost figure is a triangle with base 8 and height 9, for a total of

Sum these areas and you'll get the total area
