What is the length of the rectangle if the perimeter is 144 inches?

Answer 1

You can't tell. The perimeter doesn't tell you the length. The only thing you know

is that the length and width have to add up to 72 inches. There are an infinite

number of rectangles with different shapes that can do that.

Here are a few of them. All of these have perimeter of 144:

Length x Width

1 x 71

2 x 70

3 x 69

4 x 68

5 x 67

10 x 62

20 x 52

30 x 42

35 x 37

36 x 36
