You’re gonna figure out the area of each side first. I’d recommend labeling them by letter to help keep track. Do 8x5=40 then multiply 40 by 2 (because there are two sides that are 8x5) then do 3x4 which is 12 usually you would divide 12 by 2 to get the area of a triangle but in this case just leave it alone because there are two triangles. Then do 3x8 for the rectangle (24) then you’re gonna add all the sides together. So 40+40+12(or 6+6) +24...youre answer should me 116
Y=-3x+5 because the line crosses the y-axis at (0,5) and the slope is -3 because the rise/run saying it goes down 3 and over 1 which can be simplified to -3.
Multiply straight across:
-6 x -8 = 48
5 x 9 = 45
Simplify:
48/45 = 16/15
16/15, or 1 1/15 is your answer
hope this helps
