Answer :

Let the breadth of first rectangle be 2x and length be 3x

In another rectangle, breadth is 1 centimetres less and length is 3 centimetres less than those of the first, this is 3 : 4



4× (2x - 1) = 3 × (3x – 3)


8x – 4 = 9x – 9


-4 + 9 = 9x – 8x


x = 5


Dimension of first rectangle:


Length = 3× 5 = 15 cm


Breadth = 2 × 5 = 10cm


Dimension of second triangle:


Length = 12 cm


Breadth = 9 cm
