☆ Solution ☆

Given :-

The perimeter of the rectangular box is 60 m.

The length of the rectangular box is 10 m.

To Find :-

The area of the rectangular box.

Step-by-step-Explaination :-

Let,

The breadth of the rectangular box be b.

Now,

As we know that :-

Perimeter of the rectangle = 2 ( Length + Breadth )

Where,

The perimeter of the rectangular box = 60 m.

The length of the rectangular box = 10 m.

The breadth of the rectangular box = b.

Putting the respective value,

60 = 2 ( 10 + b )

60 = 20 + 2b

60/20 = 2b

30 = 2b

30/2 = b

15 = b

Hence,

The breadth of the rectangular box is 15 m.

Now,

As we know that :-

Area of the rectangle = Length × Breadth

Where,

The length of the rectangular box = 10 m.

The breadth of the rectangular box = 15 m.

Putting the respective value,

Area of the rectangle = 10 × 15

Area of the rectangle = 150

Hence,

The area of the rectangular box is 150 m².
