Here is your answer

Let the breadth is x
so Length is x + 3

Perimeter = 22

As we know
Perimeter = 2(L + B)
$22 = 2( x + 3 + x) \\ \frac{22}{2} = 2x + 3 \\ 2x = 11 - 3 \\ x = \frac{8}{2} \\ x = 4$
Therefore
Length = 4 + 3 = 7 units

Breadth = 4 units

Answer 2

Hey mate, here is your answer -



let the breadth of the rectangle be 'x' unit

then length of the rectangle be 'x+3' units

Perimeter of rectangle = 2( length + breadth ) = 2 ( x + x+ 3 ) = 4x + 6 .

But perimeter = 22 units. (given)
So,
4x + 6 = 22 units
4x = 22-6
x = 16/4 = 4 units.

Hence, length= 4 + 3 = 7 units.
And breadth = 4 units.
