Posted by maya on .
the floor of a room is a rectangle. it has a perimeter of 22m and an area of 24 square meters.
what are the length and width of the room?

math 
Reiny,
length  x
width  y
x+y = 11 or y = 11x
xy = 24
x(11x) = 24
x^2  11x + 24 = 0
(x3)(x8) = 0
x = 3 or x = 8
if x=3, y = 8
if x = 8, y = 3
the room is 3 by 8 
math 
Ms. Sue,
This must be a closet.
The factors of 24:
3 * 8
4 * 6
2 * 12
Which of those dimensions would give a perimeter of 22 m? 
math 
maya,
im in grade 4 i don't know what that is

math 
Ms. Sue,
Perimeter = 2 times length plus 2 times width

math 
maya,
rieny that doesent make sense it cant be.

math 
Reiny,
Maya, if you only in grade 4, then forget about my solution.
Go with what Ms Sue has shown you.
the room is 3 metres by 8 metres
check : 3+8 + 3+8 = 22
3x8 = 24 
math 
maya,
wow thanks rieny :)
