Answer:
Length = 90 inch.
width = 30 inch
Let width of the rectangle = x inch.
So the length = 3x inch.
Perimeter = 2(length + width) = 2 (3x + x) = 8x.
So,
length = 3x = 3(30) = 90 inch.
width = x = 30 inch
I know this is really late but the answer is y=-1/4x
The answer is c I took that test last tear
Your answer could be x=0.3 or
Sin = 0.299997468
