answer is 12W cm as the formula is 2*(length+breadth)=perimeter ,so w ( breadth) +5w (length) =6w (length+breadth) and then 6w *2 =12w(answer)
Ans 6:
Class : Class 7
Breadth=w,
Length is 5 times more,
Therefore, length = 5w
Therefore, perimeter=2(5w+w)
=2*6w
=12w
Hence, b is the correct answer

The correct answer is C.
In ΔAED,
∠AE D + ∠EAD + 90° = 180° (Angle sum property)
⇒ ∠AED + ∠EAD = 90°
⇒ ∠EAD = 90° – ∠AED ...(i)
Also, ∠EAD = (50° + ∠AFB) ...(ii) (Exterior angle property)
From (i) and (ii), we have
50° + ∠AFB = 90° – ∠AED
⇒ ∠AFB + ∠AED = 90° – 50° = 40°
⇒ ∠AED + ∠CFD = 40°

The first and third letters are interchanged, and their immediate next letter is taken. The 2nd, 4th and 6th letter are directly written without any change. Same happens to 5th and 7th letters. This is the pattern here.
