Totally doable. Just break it into 2 shapes rectangles and triangles.
Rectangles: A=bh so: 83×60 now since there are 3 rectangles with the same parameters multiply your answer by 3 [tex]83 \times 60 = 4980[/tex] [tex]4980 \times 3 = 14940[/tex] put aside the rectangles.
Triangles:A= 1/2×b×h so: A= 1/2 ×82× 76 Then multiply your answer by 2 since there are 2 triangles.
This will give you the answer 3116.
Now all that's left is to add the area from the rectangles and the area from the triangles.
Part 2 for your previous question. The third picture is called the Pythagorean theory. The equation is a squared + b squared =c squared. So take the meausurment of the "a" side and square it. Do the same with "b". Next add those two together then square root the answer. Refer to the next picture. That was an example.
