Question

the perimeter of a rectangle is 40 cm. the length of the rectangle is more than double its breadth by 2 find the length and breadth.​

Answer 1

Answer:

length is 11

breadth is 9

Step-by-step explanation:

the perimeter of rectangle is =2(length +breadth)

40=2(x+2+x)

40=2(2x+2)

40=4x+4

40-4=4x

36=4x

x=9

length is x+2=9+2=11

breadth is x=9

Answer 2

Step-by-step explanation:

GIVEN :-

✴ PERIMETER OF RECTANGLE = 40 CM

✴ LENGTH = 2 + BREADTH .....FROM ABOVE CONDITION

TO FIND => LENGTH & BREADTH ?

ACCORDING TO PERIMETER OF RECTANGLE = 2 ( L + B )

40 = 2 ( X + 2 + X )

40 = 2 ( 2X + 2 )

40 = 4X + 4

40 - 4 = 4X

36 = 4X

X = 36÷4

X= 9

LENGTH OF RECTANGLE = 2 + B

= 2 + 9

= 11 CM

BREADTH OF RECTANGLE = 9 CM
