Answer:

Breadth = 9

Length = 11

Step-by-step explanation:

[Let the breadth be ‘x’]

[Let the length be 2 + x = 2+x]

ATQ (According To Question)

=> 2 x [x + (2+x)] = 40

=> 2x + 4 + 2x = 40 [Multiplying by 2]

=> 4x + 4 = 40 [Adding the ‘x’s]

=> 4x = 40 - 4 [Transposing 4]

=> 4x = 36 [Subtraction]

=> x = 36/4 [Transposing 4]

=> x = 9 [Answer]

Breadth = (x) = 9

Length = (x + 2) = 11

Answer:

Breadth = 6.6

Length = 19.8

Step-by-step explanation:

Perimeter = 40

Formula of perimeter = 2(l+b)......................... 1

According to question l=2b

Putting value in equation 1

40= 2(2b+b)

40= 2(3b)

40/2= 3b

20 = 3b

20/3 = b

6.666666= b

Length = 2b

L= 2×6.66

L= 13.32

Hope u understand this
