Answer:
728 m^2
Step-by-step explanation:
There are 5 faces of the square pyramid.
You have to calculate area of each face and add them to find surface area.
Bottom face is a square, so
area = 14^2 = 196 m^2
All the other faces are triangle with same area, so
4 × triangle area
4 × ((1/2)×14×19)
4 × 133
532 m^2
Now add those areas,
(196 + 532) m^2
728 m^2
