Brief explanation with gaps in between the steps .​

Answer 1

Answer:

The perimeter of the rectangle is 16 cm

The length of the rectangle is 5 cm

Breadth =?

The formula for perimeter of the rectangle is 2(l+b)

So, 2(l+b) = 16 cm

2(5cm +b) =16 cm

10cm + b =16 cm

Now, B = 16 cm - 10 cm = 6 cm

Therefore the Breadth of the rectangle is 6 cm

The area of the rectangle = (l×b)

The length is 5 cm and The breadth is 6 cm

So, The area = 5cm×6cm = 30cm².

Therefore, The answer is 30 cm²
