Option A 84 m is the right answer. Solution : The area of square is 144 m as given. Hence, the side of square is 12 m. The length of one smaller square in the shaded square is 6 m. Hence the length of the rectangle is 6+6+6+6 =24 the breadth of rectangle is 6+6+6=18 The perimetre of rectangle is 2(l+b) = 2 (24+18) = 2*42 = 84 m

Ans is 84. Area of the square = 12 x 12 = 144 which means 12 is the length of two sides of the square, therefore each side will be 6 and there are 14 sides. Hence the perimeter is 14 x 6 = 84

The solution provided by SOF says - 1/5 ÷ 1/14 = 1/5 x 14 I am not sure about the process. Answer-(B)35This is silly!

Ans 10:

Class : Class 6
this question was very difficult . the admin doesn't know the process than how can he give it us

Ans 11:

Class : Class 6
Why is the solution not clear.I am not understanding this solution. Always I have difficulty understanding these solutions.

Ans 12:

Class : Class 8
yeah they are not clear in the solution. maybe the computer is programmed to show the specific lines of not being sure of the process

Ans 13:

Class : Class 8
according to the process the answer should be 14/5 that is 2.8

Ans 14:

Class : Class 5
THIS IS RIDICULOUS

Ans 15:

Class : Class 8
1/5 ÷ 1/14 = 1/5 x 14 I am not sure about the process. Answer-(B)35
