Consider a regular pyramid where p is the perimeter of the base, s is the slant height, ba is the base area, and la is the lateral area. what is a valid formula for the surface area? check all that apply

Let
p> is the perimeter of the base
s> is the slant height
ba> is the area of the base
la> is the lateral area

we know that
[surface area of the pyramid]=area of the base+perimeter of the base*slant height/2
so
[surface area of the pyramid]=ba+p*s/2
 la=p*s/2
[surface area of the pyramid]=ba+la

the answer is
surface area=ba+p*s/2
surface area=ba+la

Sin(a)+cos(a)+cot(a)-1=2(csc(x)+1)
