Question

The length and the breadth of a rectangle are in the ratio 2:1 . If the length is increased by 2 cm and breadth by 3 cm then the ratio of the perimeter of the new rectangle to the perimeter of the original rectangle is 4/3 . Find the dimensions of the original rectangle.​

Answer 1

Explanation:

HERE IS UR ANSWER

Let the ratio be x as 1x:2x.

Perimeter of rectangle =2(1x+2x)=6x [p=2(I+b)

If length is increased by 2 and breadth is increased by 3, then new perimeter =2(x +2+3+2x)

=6x+10

(6x + 10) / 6 * x = 4/3

3^ * (6x+10)=24*

18x + 30 = 24x

6x = 30

x = 5

Dimensions of Original Rectangle are 5 and 10 cm respectively..
