Answer 1

⭐HELLO MATE⭐

✌✌ANSWER✌✌

We know perimeter of rectangle = 2( l + b)

$2(12 + b) = 480 \\ 12 \: + \: b = 240 \\ b = 240 - 12 \\ b = 228 \: cm$

Now,

AREA = L * B

$area \: = 228 \times 12 \\ area \: = 2736 \: {cm}^{2}$

Answer 2

Answer:

2736 cm²

Step-by-step explanation:

Perimeter = 2(l + b) = 2(12 + b) = 480.

Therefore, b = 240 - 12 = 228.

Now, area = l * b = 12 * 228 = 2736 cm².
