I NEED HELP PLEASE SHOW YOUR WORK !

I believe that the answer is 95 meters.

Explanation:

Okay, so to solve this question, you must know the formula to solve for the area of a rectangle/square.

Area of a rectangle/square - l x w

In this question, you can see the the width (72 m) and the area (6840 m²) is already given. What you can do in this situation is to use the opposite operator (division) to solve for the length of the rectangular field.

6840 ÷ 72 = 95

You can always double check to see if the number is correct.

A = l x w

= 72 m x 95 m

= 6840 m²

Really hope this helped. :)
