Robert is completing construction of a square inscribed in a circle, as shown below. What should be the next step in his construction?

A circle is drawn with diameter of segment AB.

Construct a perpendicular bisector to line AB.
Place his compass on the radius and draw two arcs above and below line AB.
Make another circle from point B with the same radius as his original circle.
Draw a line parallel to line AB that touches the circle at point A.

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

have a nice day!

answer is c.

quadrilateral

hope you got it chief
