Question 279191: This is actually simple, but it has been awhile for me and need a refresh?
If rectangle has a perimeter of 30 meters, how do I write in equation ffor the area in term l ?
Make a graph of equation and describe shape, (this I don't remember)?
Use the equation to find the area of the rectangle with length of 10 meters?
I guess by my graph, I'm supposed to see this? I don't recall making graphs?
What is the maximum area possible for a rectangle with a perimeter of 30 meters and what are the dimensions of this rectangle?
It has been years, I'd say 20 since I've done this. Could someone show mw how once again and refresh this old brain?
Thanks,
Lise

You can put this solution on YOUR website! For a rectangle, you need 2 dimensions, usually called length and width.
-----------------
If rectangle has a perimeter of 30 meters, how do I write in equation ffor the area in term l ?
Perimeter = 2L + 2W
-----------------------
Make a graph of equation and describe shape, (this I don't remember)?
Use the equation to find the area of the rectangle with length of 10 meters?
The area is 10 times the width (in square meters)
------------------------------------
I guess by my graph, I'm supposed to see this? I don't recall making graphs?
I don't know what graph you refer to.
--------------------------
What is the maximum area possible for a rectangle with a perimeter of 30 meters and what are the dimensions of this rectangle?
The max area for a rectangle of given perimeter is a square --> L and W = 7.5 meters
--> Area = 7.5*7.5 = 56.25 sq meters
