Answer 11

perimeter of a rectangle is 72 find the area

Answer 12

If you really have no further info, then the best we can do is to talk in terms of variables L and W, where L = length and W = width of the rectangle.

You say the perimeter is 72. What's the formula for perimeter (of a rectangle)?

What's the formula for the area of a rectangle, given that its length is L and its width is W?

Answer 13

formula for perimeter is 2(l+b)
are l x b now???

Answer 14

@mathmale , @ParthKohli

Answer 15

L and W (not 2 and b) can't be found without further info.

What is the perimeter (as a formula)? What is the perimeter (as a number)?

Write the appropriate formula.

Also, please write the formula for the area of a rectangle (I asked you to do that earlier).

Answer 16

im confused

Answer 17

Let's start with definitions :-)

Answer 18

The perimeter of a plain figure is the distance around it. P=2l+2w

Answer 19

You are told P=72 what are the units?

Answer 20

..."plain figure" ? The perimeter of a rectangle is the sum of its sides: P=2L+2W.

Answer 21

we still need units of measure? cm, m. inches, feet...

Answer 22

its 72cm

Answer 23

Ok so 72cm = 2l+2w

Answer 24

Now for area, the area of a region is the number of square units it contains A=lw

Answer 25

and whats l and w?????

Answer 26

l = length of rectangle, w= width of rectangle

Answer 27

l is what cms
and w is what cms

Answer 28

As I told you before, we will not be able to find L and W as specific numeric values.
All you can do is the express the area in terms of L and W OR in terms of just one of them.

I explained earlier what L and W mean:

If you really have no further info, then the best we can do is to talk in terms of variables L and W, where L = length and W = width of the rectangle.
