The correct proportions are given as follows:
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The proportions for this problem are given dividing y by x, hence:
- x = 3, y = 27: 27/3 = 9, hence 9/1 has to be marked.
- x = 9, y = 81: 81/9 = 9, hence 9/1 has to be marked.
- x = 21, y = 126: 126/6 = 6, hence 6/1 has to be marked.
- x = 14, y = 84: 84/14 = 6, hence 6/1 has to be marked.
- x = 12, y = 36: 36/12 = 3, hence 3/1 has to be marked.
- x = 15, y = 45: 45/15 = 3, hence 3/1 has to be marked.

12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 479,001,600
I recommend you use this as a starter. I can't be completely sure if it's right. I hope it helps though! Good luck!
Answer:
Step-by-step explanation:
60 * 50 * 2 = 6000cm
50 * 40 * 2 = 4000cm
40 * 60 * 2 = 4800cm
6000 + 4000 + 4800 = 14800 * .04= 592
Surface area= Area of all the shapes added together
Area of square =s^2
Area of triangle =bh/2
S=12
B=12 B is s
H=8
12^2 =144 square
12×8= 96/2=48 triangle
There are 4 triangles and 1 square
144+48+48+48+48=336 Answer is f hope that helps
