A rectangle is inscribed in semicircle of radius 4m. Find the max possible area for such a rectangle
Here is what I was doing until I realized I used the wrong radius.
Sorry if it seems redundant since RedDogs fine answer, but I worked it out earlier and do not want my attempt to go in vain.
Let x and y be the dimensions of the rectangle. Then area is A=xy
Sub into A and we have:
Max area is then
Now, try the same problem with an inscribed trapezoid
