Direction (Qs. 31 and 32): Monku is doing a Math activity at his home. He prepared a chart of a shape of a square with its boundary as 16cm as given below. Look at the figure given below and answer the questions that follow:  

State true/false for the following statements. A: If a small square of side 1 cm is cut off from the corner, then the boundary will remain the same. B: If a small square of side 1 cm is cut off from the corner then the boundary will get increased. C: If a small square of side 1 cm is cut off the corner then the boundary will get decreased. D: All statements are false.

A) FTFF                          

B) TFFF

C) FFTF                          

D) FFFT

Correct Answer: B

Solution :

    Boundary of the square = 4cm + 4cm + 4cm + 4cm = 16cm. If a small square of side 1cm is cut off from its corner from the shape would become: Boundary of new shape = 4cm + 3cm + 1cm + 1cm + 3cm + 4cm = 16cm Boundary remains same. So, statement A is true and B, C, D are false. Therefore, the answer is option  TFFF.
