Question

Perimeter of the figure given below is 64 cm. Find the length of the side marked as 'x' by using the given perimeter.

• A. 22 cm
• B. 18 cm
• C. 42 cm
• D. 36 cm

Answer 1

The correct option is A 22 cm

Given, perimeter of the figure = 64 cm

Sum of the given sides = 6 cm + 2 cm + 4 cm + 18 cm + 4 cm + 2 cm + 6 cm = 42 cm

Now, perimeter of the figure = Sum of length of all the sides

$\Rightarrow$ Perimeter of the figure = 6 cm + 2 cm + 4 cm + 18 cm + 4 cm + 2 cm + 6 cm + x

$\Rightarrow$ 64 cm = 42 cm + x

$\Rightarrow$ x = 64 cm - 42 cm = 22 cm

$\therefore$ Length of the remaining side (x) = 22 cm
