Answer 2

Answer:

12 feet

Step-by-step explanation:

Perimeter of the rectangle = 16 feet

Formula = 2*(length + breadth)

2*(length + breadth) = 16 feet

Let the breadth be x

length = 3x

2*(3x + x) = 16 feet

8x = 16 feet

x = 2 feet

3x = 2*3 = 6 feet

Length = 6 feet and Breadth = 2 feet

Area = Length * Breadth

= 6 * 2

= 12 feet
