Answer 2

I got the answer of E. Correct or not?

Answer 3

This is a rectangle. A square has all congruent sides.

Answer 4

Ya it looks like the answer is E. since the sides can be different numbers that can add up to 16 as the perimeter.

Answer 5

Area of a rectangle is WxH and perimeter is 2(wxH) but not enough information is given to solve so the answer is E

Answer 6

If it can be any number as the sides of that rectangle then you won't know what the area is.

Answer 7

If we said the perimeter is 16, we can conclude that if we add a length and a width together we'll get 16/2 or 8.

So let L = the Length, and width is (8-L)
Area of a rectangle is therefore L(8-L)

We dont get a number for the area from only knowing the perimeter. SO i'd say the answer is E.

Thanks to all who helped !
