We have been asked the perimeter of the pentagon.

The right angled triangle which has length of two sides 3 and 4,
will have a hypotenuse of 5, which also happens to be the other
side of the rectangle so formed

Therefore, the perimeter is 3+4+7+5+7 = 26(Option B)

The right angled triangle will have Hyp as 5

So, the area of the pentagon will be 5 + 7 + 4 + 3 + 7 = 26

Thus, answer will be (B) 26
