You can't tell. The perimeter doesn't tell you the area, and the
area doesn't tell you the dimensions. plus it looks like your missing information on the problem dude

Answer 2

You can't tell. The perimeter doesn't tell you the area, and the
area doesn't tell you the dimensions.

Here's a little example. ALL of the rectangles on this list have
the same perimeter ... 72 inches:

1 x 35 . . . . . Area = 35 square inches
2 x 34 . . . . . Area = 68 square inches
3 x 33 . . . . . Area = 99 square inches
4 x 32 . . . . . Area = 128 square inches
5 x 31 . . . . . Area = 155 square inches
6 x 30 . . . . . Area = 180 square inches
10 x 26 . . . . . Area = 260 square inches
15 x 21 . . . . . Area = 315 square inches
18 x 18 . . . . . Area = 324 square inches .
