A rectangle has the vertices at 0,0 3,0 and 0,6 what is the area of the rectangle

The rectangle will be 3 units by 6 units so it will be 18 units^2

The larger lengths of the rectangle are discovered because 0,0 -> 0,6. The y value has increased by six units.

The smaller lengths of the rectangle can be determined by 0,0 -> 3,0. The x value has increased by 3 units.

If we needed to discover the last vertices, it would be at 3,6.

Cthe residual plot for model 1 has a non random pattern and is a good fit for the data
