Question

A rectangle has an area of 16 square feet. What is its maximum perimeter?

Answer 1

16

Answer 2

no, not 16, if x=16 and y=1 perimeter is 16+16+1+1=34 which is more than 16, maximum perimeter is infinity i think when x is very big and y is very small

Answer 3

it is maximum and it is for a square and for rectangles it sud be less than 16

Answer 4

i said 3.

Answer 5

for rectangle it should be
Area = 16ft^2
x*y = 16ft^2
now find out x & y

Answer 6

so 16 is not maximum perimeter, because 16 is only when x and y are equal to 4, but if x=16 and y =1? what's perimeter then?

Answer 7

the p=34 i think

Answer 8

yeah thats true

Answer 9

maximum perimeter is infinity..........

Answer 10

so yeah as i said before that it's infinity, and it's probably mistake in question, it should have asked for minimum perimeter

Answer 11

so than A=16 we can getting this from 4*4 or 2*8 or 16*1- just using integers - hence we get the greater perimeter using sides dimensions 16 and 1 because than we get 16+16+1+1=34

Answer 12

it doesn't say that we can use only integers
