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
