The area of a rectangular field is 99m2. The length of one side is 11m. The farmer needs to know its perimeter to work out how
much fencing will be needed? Help

40 m

Step-by-step explanation:

Hi there!

What we know:

1) Find the length of the other side

Plug all the given information into the area formula for a rectangle:

where A is the area, l is the length and w is the width

Divide both sides by 11 to isolate w

Therefore, the width of the field is 9 m.

2) Find the perimeter of the field

where l is the length and w is the width

Plug in the length (11 m) and the width (9 m)

Therefore, the perimeter of the field is 40 m.

I hope this helps!

the answer is 1030 it's very simple math.
