The pyramid is made up of 1 square and 4 identical triangles. You have the length of one side of the square (14) and you have the length of the base (14) as well as the height (19) of the triangle. Calculate the area of the square and the four triangles (or one triangle and multiply by four) and add your results to obtain the area for the pyramid.

What's the problem? You need the area of the object. Carefully look at the pyramid and see how you can deconstruct it into figures that you are capable of finding the area of. Inspection of the pyramid shows it is made up of a square at the bottom of length 14m and  you can also see an isosceles triangle of height 19m where a line is marked 19m. Inspecting further you can see there are three more triangles surrounding the square. Each of these triangles has a base of 14m and a height of 19m. The area of the pyramid will be the sum of the area of the square and the four triangles.

The area of the square is $$(14m)^2 = 196m^2$$
and the area of one triangle is$$\frac{ 14*19 }{ 2 }= 133m^2$$
The area of all 4 triangles will be $$4*133=532m^2$$
The total area will then be
$$(196+532)m^2=728m^2$$
