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
