The area of a rectangular field is 6840 m2. If the width of the field is 72m , what is its length?
IgorLugansk [536]

Answer:

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.

<em>Area of a rectangle/square - </em><em>l x w</em>

<em />

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.

<em>6840 ÷ 72 = </em><em>95</em>

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

<em>A = l x w</em>

<em>= 72 m x 95 m</em>

<em>= </em><em>6840 m</em>²

Really hope this helped. :)
