Question

A square of side 2 cm is cut out from a corner of a square of side 4 cm. What is the perimeter of the resulting figure?

• A. 20 cm
• B. 18 cm
• C. 16 cm
• D. 12 cm

Answer 1

The correct option is C 16 cm


The perimeter of the resulting figure is

$4\text{cm}+4\text{cm}+2\text{cm}+2\text{cm}+2\text{cm}+2\text{cm}=16\text{cm}.$

Note that this is same as the perimeter of the larger square.

$(16\text{cm}=4\times a=4\times (4\text{cm}\left)\right)$
