The lateral area and total area would require knowing the size of that square base.
The problem does not provide that information directly,
but the length, , of the base sides
can be calculated from the information given.
A top view, and a cross section of the pyramid
(cutting across the middle of opposite lateral faces)
would look like square and the isosceles triangle below
Applying the Pythagorean theorem to right triangle ABC,
--> --> --> --> --> .
The lateral faces are triangles with base and height ,
so the lateral area is
square units
(of whatever units was used to measure pyramid height and slant height).
The area of the square base is square units,
so the total area (in square units) is
square units.
