Question

The area of each square in the given figure is 4 cm². The perimeter of the whole figure will be

• A. 24 cm
• B. 28 cm
• C. 20 cm
• D. 44 cm

Answer 1

Answer: (B), (D)

The correct options are
B

28 cm

D

44 cm

Area of square = side $\times$ side
$\therefore$ side $\times$ side = 4 cm²
$\Rightarrow$ side = 2 cm.
Now, looking at the figure we can say that:
Length of the bigger rectangle = 5 $\times$ 2 cm = 10 cm
And Breadth of the bigger rectangle = 2 $\times$ 2 cm = 4 cm
$\therefore$ Perimeter of the bigger rectangle = 2 $\times$ ( Length + Breadth)
= 2 $\times$ (10 + 4) = 28 cm.
