Question

The area of each square is in the given figure is 4 cm². Find the perimeter of the whole figure in cm.

• A. 28

Answer 1

The correct option is A 28
Area of square = side $\times$ side
$\therefore$ side $\times$ side = 4 cm²
$\Rightarrow$ side = 2 cm

Now,
Length of the bigger rectangle = 5 $\times$ 2
= 10 cm
Breadth of the bigger rectangle = 2 $\times$ 2
= 4 cm
$\therefore$ Perimeter of the bigger rectangle
= 2( Length + Breadth)
= 2(10 + 4)
= 28 cm
