The rectangular equation which represents the parametric equations x =t^(1/2) and y = 2t is; y=2x².
According to the task content;
It follows that the parametric equations given are; x =t^(1/2) and y = 2t.
Since x =t^(1/2), then it follows that; x² = t.
Therefore, by substituting x² for t in y= 2t, then we have; y = 2x².
