Question

The ratio of length and breadth of a rectangle is 3 : 2 respectively. The respective ratio of its perimeter and
area is 5:9. The breadth of the rectangle (in m) is​

Answer 1

Answer:

Let The length be 3x and breadth be 2x.

The ratio are area and perimeter 5 and 9

2(2x+3x)/6x²=5/9

4x + 6x/6x²= 5/9

10x/6x²=5/9

10/6x=5/9

30x=90

x=3

breadth =3*2=6

Answer 2

Step-by-step explanation:

Let length =5x and breadth=2x

Area of rectangle=5x×2x=10x2

Perimeter of rectangle=2(l+b)=2×(5x+2x)=14x

Now, AP=31⇒10x214x=31⇒x=4.2

∴Length of rectangle=5×4.2=21 units.
