Area of first rectangle = 4*3=12
Area of second rectangle = 7*8=56
Area of third triangle is 1/2*bh=1/2*3*8=12
Now add all the three 12+12+56=80
So area is 80 square cm

Part A.) is 39 because 13+7= 20+4=24+4=28+3=31 and I'm assuming that side that doesn't have a number is 8 so your final answer would be 39
I basically gave you part b but word it differently. Don't say that your assuming that one side is 8.
I hope I helped if i did Mark me as brainliest .
