Question

the perimeter of the rectangular is 20 CM if the length of the rectangle is 6 then what is the breadth of the rectangle​

Answer 1

Given :

• Perimeter of Rectangle = 20cm
• Length of Rectangle = 6cm

To Find :

• Breadth of Rectangle.

Solution :

$\longmapsto\tt{Length=6cm}$

Using Formula :

$\longmapsto\tt\boxed{Perimeter\:of\:Rectangle=2(l+b)}$

Putting Values :

$\longmapsto\tt{20=2(6+b)}$

$\longmapsto\tt{\cancel\dfrac{20}{2}=6+b}$

$\longmapsto\tt{10=6+b}$

$\longmapsto\tt{10-6=b}$

$\longmapsto\tt\bold{b=4cm}$

So , The breadth of Rectangle ia 4cm..

VERIFICATION :

$\longmapsto\tt{20=2(l+b)}$

$\longmapsto\tt{20=2(6+4)}$

$\longmapsto\tt{20=2(10)}$

$\longmapsto\tt\bold{20=20}$

Answer 2

Step-by-step explanation:

Perimeter of Rectangle = 2(l+b) = 20 cm

Length (l) = 6cm

Breadth = x cm

Perimeter = 2 ( 6 + x ) = 12 + 2x = 20cm

Perimeter = 2x = 20-12

Perimeter = x = 8/2

Breadth = 4cm
