Answer 2

Hey friend

Given-:
Perimeter of rectangle=130cm
Breadth of Rectangle= 30cm

To Find-:
Length of rectangle=?
Area of rectangle=?

Solution-:
Let the Length be 'X'.

Now,

=>Perimeter of Rectangle= 2[L+B]
=>130cm=2[X+30]
=>65cm=X+30
=>X=35cm

So, the length of rectangle=35cm

Now,

=>Area of Rectangle=Length×Breadth
=>Area of Rectangle=30×35
=>Area of Rectangle=1050cm²

So, the area of Rectangle=1050cm²
