Question 1126429
<br>
The right angle is at (0,y) = (0,sqrt(x)).<br>
One leg is from (0,sqrt(x) to (0,0); length = sqrt(x).
The other leg is from (0,sqrt(x) to (x,y) = (x,sqrt(x)); length x.<br>
The area of the triangle is half the product of the lengths of the legs:<br>
{{{A = (x*sqrt(x))/2}}}<br>
You can draw the sketch.
