No one is obtouse and one is acute
Answer:
(-6,4)
Step-by-step explanation:
make sure x's or y's are the same and opposite signs
x + 2y = 2 and -2x +y = 16
multiply 2 with x + 2y = 2 so that there is 2x
2 * (x + 2y = 2) = 2x + 4y = 4
2x + 4y = 4
-2x +y = 16
--------------------
5y = 20
y = 4
put y = 4 back into one of the equations
-2x +y = 16
-2x + 4 = 16
-2x = 12
x = -6
I have to assume that you mean it is a similar rectangle, since a triangle can not be similar to a rectangle. In that case the original measurements are 4x4.5.
By doubling them, you get a rectangle with the measurements of 8x9 and thus the area is 72
