a rectangular field is 85 meters wide and 125 meters long. give the length and width of another rectangular field that has the same perimeter but a smaller area. width = meters length = meters

Explanation:

Step1: Calculate original perimeter

$P = 2\times(85 + 125)=420$ meters

Step2: Choose new dimensions

Let width be 10 and length be 200 (sum is 210, so perimeter is 420).

Step3: Calculate areas

Original area: $85\times125 = 10625$ square - meters. New area: $10\times200 = 2000$ square - meters.

Answer:

width = 10 meters
length = 200 meters
