Question

The perimeter of a rectangular field is 60 m.

What are three possible measurements
of the field? Use dimensions to the
nearest meter.

Answer 1

10m by 20m

12 m by 18 m

14m by 16m

Explanation:

The perimeter of a rectangle is

P = 2(l+w)

60 = 2(l+w)

Divide each side by 2

30 = l+w

Let l = 10

Then w = 30 - 10 = 20

Let l = 12 then w = 30 - 12 = 18

Let l = 14 then w = 30 -14 = 16
