Answer 2

Given :

• Perimeter of rectangle is 320 cm.
• Sides of the rectangle in the ratio of 5:3.

To find :

• Area of Rectangle =?

Formula Used :

• Perimeter of the rectangle = 2(length + breadth)
• Area of Rectangle = length x breadth

Step-by-step explanation :

Let, the length of the rectangle be, 5x.

Then, the breadth of the rectangle be, 3x.

As We know that,

Perimeter of the rectangle = 2(length + breadth)

And it is a given that,

Perimeter of rectangle is 320 cm.

As per question,

320 = 2(5x + 3x)

320 = 2 × 8x

320 = 16x

x = 320/16

x = 20.

Therefore, We got the value of, x = 20.

Hence,

The length of the rectangle, 5x = 5 × 20 = 100 cm.

Then, the breadth of the rectangle, 3x = 3 × 20 = 60 cm.

Now,

As We know that

Area of Rectangle = length x breadth

Substituting the values in the above formula, we get

= 100 × 60

= 6000

Therefore, the area of rectangle = 6000 cm².
