correst sentence would be absolute value is how far number is from 0
I did not even understand that equation
The answer is the last one; to express very large or small numbers.
We use it so we can show big or very small numbers in an easier way.
The base is a square, therefore all the sides of the base are the same. This also means all the triangles have the same area.
10*10 = 100 cm^2 for the base
0.5*10*12 = 60 cm^2 for each triangle
100 + 4(60) = 340 cm^2
