Answer 1

Answer:

The perimeter of the rectangle is 98cm.

Step-by-step explanation:

What do you recall from the formula that we have learnt about the area of the rectangle?

Area of rectangle = Length × Breadth

We are given with the data that the area of a rectangle is 600cm².

Now, we know that,

Length × Breadth = 600 cm²

$\implies \bf x \times 25cm = 600cm^{2}$

$\implies \sf x = \dfrac{600cm^{2}}{25cm}$

$\implies \sf x = 24cm$

So, now we know that the length of the rectangle is 24cm.

Now, let's find the perimeter of the rectangle as we know that,

Perimeter of rectangle = 2(l + b)

The perimeter of rectangle = 2(24 + 25)

The perimeter of rectangle = 2(98)

The perimeter of rectangle = 98cm.

Answer 2

Correct Question-:

• Find the perimeter of of a rectangle whose area is 600 cm² and breadth is 25 cm .

AnswEr -:

• Perimeter of Rectangle is 98 cm .

Explanation-:

Given ,

• Area of Rectangle is 600 cm² .
• Breadth of Rectangle is 25 cm .

To Find ,

• Perimeter of a Rectangle.

Solution -:

As , We know that ,

• Area of Rectangle is -;

$\sf{\rightarrow { A = l \times b }}$

Here ,

• A = Area = 600 cm² .
• L = Length = ?
• B = Breadth = 25 cm

$\sf{\rightarrow { l \times 25 = 600 \:cm² }}$

$\sf{\rightarrow { l = \frac{600}{25}}}$

$\sf{\rightarrow { l = 24 cm }}$

Therefore,

☆ Length of Rectangle-: 24 cm . ........ 1

As , We know that ,

☆ Perimeter of Rectangle-:

• $\sf{\rightarrow { P = 2(l + b) }}$

Here ,

• P = Perimeter = ? .
• L = Length = 24 cm . .............. [ From 1 ]
• B = Breadth = 25 cm

$\sf{\rightarrow { P = 2(25+24)}}$

$\sf{\rightarrow { P = 2 \times 49 }}$

$\sf{\rightarrow { P = 98\: cm}}$

Hence ,

• Perimeter of Rectangle is 98 cm .
