What is the surface area of the triangles prism?? 13 points please give the right answer
1 answer:
First, let's calculate the triangles of the prism. The area of a triangle is base times height, then divide by 2. So: (7*8)/2. This would give us 28. Also knowing that there are two triangles on the prism, we have to multiply 28 by 2. This would give us 56. Now, for the rectangles, we have to find their areas. The area of a rectangle is length times width. So this would give us: 8*16. This equals 128. Next, knowing that there are three rectangles, multiply 128 by three. This gives us 384. Now, we jus have to add all the areas together: 384+56 = 440 So the prism's surface area is 440cm^2 Hope this helps. If you have any questions, please put them in the comments below.

Step-by-step explanation:
The answer is -125+85= -40 because she is adding -125 by 85 which equals-40
Draw up a right triangle to connect these two points with the line itself being the hypotenuse. Then use pythagorean theorem to solve for the hypotenuse
