Question

breadth?
(A) 6 cm (B) 12 cm (C) 3 cm (D) 2 cm​

Answer 1

$\huge\mathtt{Hello!}$

Perimeter of the rectangle = 36 cm

Let us say,

Breadth of the rectangle = b

Length of the rectangle = 2b

Perimeter of rectangle = 2(l+b)

$36 = 2(b + 2b)$

$36 = 2 \times 3b$

$b = \frac{36}{6}$

$b = 6cm$

Therefore, breadth is 6cm - Option A
