Answer:
Perimeter: 33.7 mm
Area: 54 mm
Step-by-step explanation:
If you do 12 + 9.7 + 12 you will get the perimeter, and to get the area you would use the formula A =
x base x height. Since the base is 12 and the height is 9, you would do 12 x 9 x 0.5 to get 54 mm for the area of the triangle.
The way I would do it is by rounding 8.91 up to 9 and I would round 34,871.081 up to 35,000.
9*35,000=315,000
Hopefully I was able to help in some way.
First find the area of the triangle: (4 x 6) ÷ 2 = 12
Then the area of the rectangle: 6 x 8 = 48
Last combine: 48 + 12 = 60
Lol, sorry~
Hope this helped tho
