Question

Answer 1

hope it helps you out dude

Answer 2

Area of rectangle=length×breadth

But all sides are same so, we can consider this rectangle as square....

Area of square =Side×Side

let the sides be x

9= x(x)
9=x2
X=3cm

therefore it's all sides are 3cm in length.

Now, perimeter of the square=4×side
perimeter=3×4
perimeter=12cm

therefore, perimeter of the rectangle is 12cm
