Question

Find the perimeter of the given rectangle (all the lengths are in cm).

• A. 52 cm
• B. 62 cm
• C. 72 cm
• D. 82 cm

Answer 1

The correct option is B 62 cm

In a rectangle, opposite sides are parallel and equal in length.
$\therefore 2(x+3)=x+8$
$\Rightarrow 2x+6=x+8\Rightarrow x=2\text{cm}$

$\therefore$ Perimeter of the rectangle
= 2 (Length + Breadth)
= 2 [(x + 8) + (6x + 9)]
= 2 [10 + 21]
= 2 × 31
= 62 cm
