Question

Which of the following has the same area as that of a square of side 4 units?

• A.
• B.
• C.
• D. None of the above

Answer 1

The correct option is A

Option 1 :
If we cut the lower triangle and paste it to the right hand cut off region, we will get a square like this.

Option 2 :
This will not be a square as there is an extra lower part.
Total area = Area of a square + Area of triangle


Option 3: This will also not result in a square as it less than the area of the square.
Total area = Area of the square - Area of the triangle


$\therefore$ Option 1 is the correct figure.
