c. it was greater than 18.96% if interest was compounded daily but not if interest was compounded monthly.

d. it was less than 18.96% if interest was compounded daily but not if interest was compounded monthly.

Option B is correct, that is It was greater than 18.96% whether interest was compounded daily or monthly.

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to
