Question

the perimeter of a rectangle is 20 centimetres.the length is 6 centimetres.
what is the area of the rectangle?​

Answer 1

Answer:

perimeter= 4

Step-by-step explanation:

20=2(l+b)

20=12+2b

-2b=12-20

-2b=-8

b=-8/-2

b=4

Answer 2

Area Of Rectangle = 24 cm²

Step-by-step explanation:

GIVEN

Perimeter = 20 cm

Length = 6 cm

___________________________

To Find

Area Of Rectangle

___________________________

We know that,

Perimeter Of Rectangle = 2 ( Length + Breadth )

20 cm = 2 × ( 6 + B)

Breadth = ( 20 - 12 ) / 2

Breadth = 8 / 2

Breadth = 4 cm

___________________________

Now,

Let's find the area of rectangle

Area Of Rectangle = Length × Breadth

Area Of Rectangle = 6 × 4

Area Of Rectangle = 24

Area Of Rectangle = 24 cm²
