Length=36 cm
Breadth/width=12cm
So the rectangle is 3x by x
We are given the perimeter, so well solve with that.
All four sides equal 3x+x+3x+x=8x
So 8x=96
When we solve for x, we get x=12
Since x=12, we know this is the breadth.
We know 3 times this is the length so:
12x3=36!
Answer:
(-11, -12)
Step-by-step explanation:
we need one variable to x out
on the note of x, lets cancel out the xs
6x+3y=-102
3x+y=-45 < same as 6x+2y-90
6x+3y=-102
-
6x+2y=-90
y=-12
substitute y in
3x-12=-45
3x=-33
x=-11
(-11, -12)
