Let
<span>p ----------------> is the perimeter of the base
</span><span>h ---------------> is the height
</span><span>BA-------------> is the area of the bases
</span><span>LA--------------> is the lateral area
we know that surface area is </span><span>the sum of base areas plus lateral areas
</span><span>then
SA=[BA]+P*h
but remember that
LA=P*h
then
SA=</span>[BA]+LA----------> SA=BA+LA
the answer are the options B.) SA=BA+LA and the option D.) SA=BA+ph
