By inspection, LMNO is similar to PQRS.
For similar figures, corresponding sides are proportional, therefore

LM/PQ=MN/QR
Substituting values
4/2=6/c
Cross-multiply
4c=6*2=12
c=12/4=3

Check the picture below.

so the surface area of the pyramid will be the sum of the areas of the base and the four triangular faces.

$\stackrel{\textit{\Large Areas}}{\stackrel{\textit{4 triangular faces}}{4\left[ \cfrac{1}{2}(7.5)(16) \right]}~~ + ~~\stackrel{\textit{rectangular base}}{(7.5)(7.5)}}\implies 240~~ + ~~56.25\implies 296.25~ft^2$
