Here is your answer

Let breadth be x
So, Length = x + 3

As we know the formula,

Perimeter of rectangle = 2(l + b)

$22 = 2(x + 3 + x) \\ \\ \frac{22}{2} = 2x + 3 \\ \\ 11 = 2x + 3 \\ \\ 2x = 11 - 3 \\ \\ 2x = 8 \\ \\ x = \frac{8}{2} \\ \\ x = 4$
Therefore,

Breadth = 4cm

Length = 4 + 3

= 7cm

Answer 2

Heyy Buddy ❤

Here's your Answer..

Let the Breadth of the rectangle be x cm.

=> Length = (3 + x) cm

Now,

PERIMETER of RECTANGLE = 2( l + b)

=> 22 = 2 ( 3 + x + x)

=> 22/2 = 3 + 2x

=> 11 = 3 + 2x

=> 2x = 8

=> x = 4cm.

Now,

Breadth = 4cm

And Length = 3 + 4 = 7cm.
