Question

The length of the rectangle is tripled and the breadth is halved. Find the new area​

Answer 1

Let the length of current rectangle be x and breadth be y

so, Length of new rectangle = 3 × length of x

= 3x

and, breadth of new rectangle = half of y

=y/2

So, Area of new triangle = l×b = 3x × y/2

=3xy/2
