Answer 2

$\sf{\huge{\underline{\pink{Given :-}}}}$

The length of a rectangle is 4 cm more than its breadth .

The perimeter is 84 cm.

$\sf{\huge{\underline{\orange{To\:Find :-}}}}$

• Length + Breadth

• The length and breadth of the rectangle.

$\sf{\huge{\underline{\red{Answer :-}}}}$

According to the question,

The length of a rectangle is 4 cm more than its breadth .

Let the length of be x

& the breadth be ( x + 4 )

The perimeter is 84 cm.

The perimeter of a rectangle = 2 ( L + B )

2 ( L + B ) = 84

➝ 2 ( x + x + 4 ) = 84

➝ 2 ( 2x + 4 ) = 84

➝ 4x + 8 = 84

➝ 4x = 84 - 8

➝ 4x = 76

➝ x = 76/4

➝ x = 19

• the length = x = 19 cm

• the breadth = ( x + 4 ) = 19 + 4 = 23 cm

Length + Breadth

➝ ( 19 + 23 ) cm

➝ 42 cm
