Answer:
624
Step-by-step explanation:
the area of the triangles:
12*10 = 120
120/2 = 60
since there are 2 triangles of the same dimensions that make up the surface area 60 + 60 = 120
area of the rectangles:
13*14 = 182
since there are 2 rectangles of the same dimensions 182 + 182 = 364
The last rectangular:
10*14 = 140
add all areas:
120 + 364 + 140 = 624

You don't need to create 3 posts for a single question. I already answered it in your most recent one.
Remember
(ab)/c=a(b/c)
and
b/b=1 when b=b
1.
8+9t+4=
8+4+9t=
12+9t=
9t+12
2. (56ab)/b=56a(b/b)=56a(1)=56a
3. divising negatives yeilds positive
-46/-2=46/2=23
(7x + 2 + 8x^4) – (2x – 5 – 8x^4) + (3x + 5x^4)
= 7x + 2 + 8x^4 – 2x + 5 + 8x^4 + 3x + 5x^4
= 8x + 7 + 21x^4
= 21x^4 + 8x + 7
