Answer:
The rectangle has rotational symmetry of order = 2
The rectangle's rotational symmetry occurs for angles of 90 degrees.
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!
