Answer 2

Step-by-step explanation:

Let the breadth of the rectangle is b cm.

So, the length of the rectangle is 2b cm.

We know that the perimeter of rectangle is

=2(l+b)

Since, perimeter of rectangle is 90 cm.

Therefore,

6b=90

b=16 cm

And l=32 cm

So, the area of rectangle is

=16×32=512 cm²

Hence, the length is 31 cm, breadth is 16 cm and area is 512 cm².
