Question

Figure P is made up of six identical squares. Two squares were removed from figure P to form figure Q. The perimeter of figure P is 240 cm. What is the perimeter of figure Q?

• A. $220cm$
• B. $180cm$
• C. $200cm$
• D. $160cm$

Answer 1

Answer: (C)

$200cm$

Let the side of each square be x.
So, perimeter of figure P = 12x
$\Rightarrow 240=12x\Rightarrow x=20cm$
$\therefore$ Perimeter of figure Q = 10x
= $10\times 20=200cm$
