A bird drops a stick to the ground from a height of 80 feet. The equation 0 = -16^2 + 64x + 80 gives the number of seconds that have passed when it hits the ground. After about how many seconds did the stick hit the ground?

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!
