Answer :
The surface area of the square pyramid is 6000 square meters.
How to find the lateral area of the pyramid?
We have a square pyramid, so the surface area is the area of the 4 triangles plus the area of the square base.
We know that the base has a length of 60 meters, then the area of the base is:
B = (60m)^2 = 3,600 m^2
And for each triangle, the area is:
A = b*h/2
where b is the base of the triangle and h is the height.
Here we have:
- b = 60m
- h = 20m
So the area of each triangle is:
A = 60m*20m/2 = 600m^2
Finally, the whole area of the pyramid is:
area = 4*600m^2 + 3,600m^2 = 6,000 m^2
