Breadth=w,
Length is 5 times more,
Therefore, length = 5w
Therefore, perimeter=2(5w+w)
=2*6w
=12w
Hence, b is the correct answer
Ans 4:
Class : Class 6
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)

How can you change 2 to 3? and how can you mark division symbol as addition and subtraction? SOF DON'T DO SUCH MISTAKES OR WE'LL HAVE TO REPORT IT TO sofworld.org
Ans 9:
Class : Class 8
the division sign represents both addition and subtraction and we can get to different answers
Ans 11:
Class : Class 7
Then the calculation will turn to 20 +8/4x3x2,
=20+2x3x2,
=20+6x2,
=20+12
=32,
so there is a problem in the question
Ans 13:
Class : Class 7
yes please correct. There are 2 division signs which represent addition n subtraction which leads to various answers
Ans 16:
Class : Class 6
There is problem in the Q as it mentions division sign represents both addition and substraction
Ans 20:
Class : Class 8
The divisions sign is used in 2 places, but I think it means subtraction because '-' meaning subtraction is not exactly coding anything...And in that case 20 8/4-3x2=20 2-6=16...Which is not an options for whatever weird reason

Ans 1: (Master Answer)
Class : Class 1
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°
