Clairs rectangular garden is 3m long and 2m wide. She wishes to expand the garden so it has an area of 20m^2. How wide a strip must she add around the edge of the garden to accomplish this task.
Help?
What is the current area? How much area must be added?
Please stop tagging me its kinda annoying
Hello Aravindg
?
Well it doesn't state the current area.
I give you a medal for asking for help
No, but it gives you enough information to figure it out.
Bye bye i got noobs to quickscope
What is the formula for the area of a rectangle?
ahh so we have to do 1/2 bh?
No, that's area of a triangle.
For a rectangle, \[A=l*w\]
Okay, so the area= 6m
Right. Can you draw a picture of current rectangle with border that we ave to construct?

right?
Correct. Now, can you label the diagram with the current dimensions, and the dimensions the new garden will have, if the width of the border is \(x\)?
you can click on the little pencil icon in the drawing post you made to recycle that drawing
