Write a variation equation the number of hours it takes to collate the pages for copies of a book is inversely proportional to the number of people doing the collating. suppose that a crew of 4 people takes a total of 12 hours to do the job.

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!

30,40,50 is correct answer
