Answer 1

Answer:

$\boxed{\sf 200 \ feet^2}$

Step-by-step explanation:

The 3D shape is a square-based pyramid.

The surface area of a square-based pyramid is given as:

$\sf SA=2 \times (base \ length) \times (slant \ height) + (base \ length)^2$

Plug in the values.

$\sf SA=2 \times 10 \times 5 + 10^2$

$\sf SA=100 + 100$

$\sf SA=200$
