P=l+b×2 L=5w B=w =5w+w×2 =6w×2 =12w cm

Breadth=w, Length is 5 times more, Therefore, length = 5w Therefore, perimeter=2(5w+w) =2*6w =12w Hence, b is the correct answer

Then the calculation will turn to 20 +8/4x3x2, =20+2x3x2, =20+6x2, =20+12 =32, so there is a problem in the question

actually! it is 32...........plz correct it

## Ans 7:

Class : Class 6
the division sign represents both addition and subtraction and we can get to different answers

Class : Class 6
Ya there is a problem...............answer is 32 you seee

## Ans 10:

Class : Class 6
yes, and should be 32, which is not an option. Pl. correct this

## Ans 11:

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°

In the 1st column, 2 X 1 + 1 = 3,

In the 2nd column, 12 X 9 + 9 = 117

Similarly, In the 3rd column, 7 X 14 + 7 = 105

Hence, the missing number is 7.
