Question

Find the missing side if the perimeter of the given figure is 32 cm.

• A. 5 cm
• B. 9 cm
• C. 8 cm
• D. 6 cm

Answer 1

The correct option is D 6 cm

Perimeter = sum of all sides
32 cm = 5 cm + 6 cm + 7 cm + 8 cm + the missing side
$\Rightarrow$ 32 cm = 26 cm + the missing side

To find the missing side, we need to subtract the sum of the known sides from the perimeter.
$\Rightarrow$ The missing side = 32 cm - 26 cm
= 6 cm
