Answer:
Step-by-step explanation:
The surface area of a square pyramid is the sum of the area of the squared base + 4 times the area of each triangular face, therefore:
where:
is the area of the base, where
L is the length of the base
is the area of each triangular face, where
h is the height of the face
Substituting,
For the model in this problem,
L = 12
h = 8
Therefore, the surface area here is:
It is given in the question that
M is the MIDPOINT OF FG.
Since M is the midpoint of FG, therefore GM is half of FG. That is
Therefore
And FM is 13 too .
