What is the area of the largest triangle that can be fitted into a rectangle of length l units and width w units?
Let ABCD be the rectangle of length l and width w.
Now,we construct a triangle of maximum area inside it in all possible ways.
We know that,
Area of triangle = × base × height
So ,for maximum area ,base and height of maximum, length is needed.
Here, maximum base length = l
And maximum height = w
Area (maximum) of triangle = × l × w sq.units.
