A rectangular field has an area of 162 m² the width of this field is 9m what is the perimeter of this field

54 m

Step-by-step explanation:

Alrighty, what have we here: an area of 162 m² and a width of 9m.

So: A=162m², W=9m, let's draw this: (see the screenshot attached)

Using the formula for area (Area = width x length) we see that:

Thus: (equating to L by dividing both sides by 9m)

⇒

Now we have all of our dimensions, we can use the formula for the perimeter to calculate it:

And there we have our answer.

x=6 and x=3
