Question

The perimeter of rectatangular plant is 120 cm if the length is 40 cms find its breadth

Answer 1

HEYA...

HERE IS UA ANSWER:

GIVEN:

PERIMETER OF RECTANGLE= 120cm

LENGTH OF RECTANGLE= 40cm

THEREFORE BREADTH:

2 ( l +b ) = 120 cm

2( 40 + b) = 120cm

80 +2b = 120

2b = 120 - 80

2b = 40

b = 40/ 2

or b = 20 cm

Answer 2

$\bold {Heya Friend}$

We know that,

Perimeter of a rectangle-

$\boxed2(l+b)$

Given=>> Perimeter = 120 cm
Length= 40 cm
Breadth = ?

Therefore,

By the formula,

$\boxed{2 (l+b) = 120cm}$

$\boxed{2 (40+b)= 120cm}$

$\boxed{40+b = 60cm}$

$\boxed{b = 20 cm}$

So, by the above calculation we get 20 cm as a breadth of plant.
