Answer 2

Step-by-step explanation:

Let the breadth of the rectangle = x metres.

According to the question, Length of the

rectangle = 2x metres Perimeter of a rectangle =

2 (length + breadth) So, 2 (2x + x) = 228 ⇒ 2 (3x)

= 228 ⇒ 6x = 228 Dividing both sides by 6, we

get ⇒ 6x/6 = 228/6 ⇒ x = 38 So, the breadth of

the rectangle = x = 38 metres, The length of the

rectangle = 2x = 2(38) = 76 metres.
