It would be B. because it's just 7 times 1.5
<h2>
Answer:</h2>

<h2>
Step-by-step explanation:</h2>
This is a square pyramid because it's a solid having a square base. The point up the pyramid is called the apex and is directly above the middle of the square base. The surface area of a solid is the total area of its outer surface. If we unfold this pyramid, we'll get one square and four identical triangles. So the surface are can be calculated as follows:

FOR THE SQUARE:
FOR THE TRIANGLE:

Finally:

Answer:
Total number of sections= 8
p(red)= 3/8
p(yellow)= 2/8= 1/4
p(blue)= 3/8
Subtract normally as if 32.6 is 316 and 1.9 is 19. Then you move the decimal point two places to the left of the answer
the answer is 29.7
First you do 3 to the 2nd power which is 9 then you just add 12+9+50= 71
