Option A:

Option C:

Solution:

To find the area of the shaded region:

Number of squares in one row = 12

Number of squares in one column = 6

Note that:

Number of squares shaded in one row = 3

Number of squares shaded in one column = 3

Option A:

Area of the shaded region  

Hence it is true.

Option B:

Already proved in option A.

Hence it is not true.

Option C:

By option A,

Area of the shaded region =

Divide the numerator and denominator by the common factor.

Hence it is true.

Option D:

Already proved in option C.

Hence it is not true.

Option E:

Here, the number of squares shaded in row indicated as 4.

But the shaded squares in row wise is 3.

Hence it is not true.

Therefore Option A and Option C are true.

  and   are true.

the answer is: the length is 5/6 yards.
