Question

the area of rectangle is 25 cm and its length is 15 cm find its breath and its perimeter

Answer 1

Given

• Area of the rectangle = 25 cm²
• Length of the rectangle = 15 cm

⠀

To find

• Perimeter of rectangle.
• Breadth of rectangle.

⠀

Solution

• Let the breadth of rectangle be b.

⠀

⠀⠀⠀❍ We know that

$\: \: \: \: \: \: \: \: \: \: \: \: \boxed{\tt{\bigstar{Area_{(Rectangle)} = l \times b{\bigstar}}}}$

⠀

$\tt:\implies\: \: \: \: \: \: \: \: {Area = 25 }$

⠀

$\tt:\implies\: \: \: \: \: \: \: \: {15 \times b = 25}$

⠀

$\tt:\implies\: \: \: \: \: \: \: \: {b = \dfrac{25}{15}}$

⠀

$\tt:\implies\: \: \: \: \: \: \: \: {b = \dfrac{5}{3}}$

⠀

$\bf:\implies\: \: \: \: \: \: \: \: {b = 1.66cm}$

⠀

Hence,

⠀⠀⠀⠀⠀⠀⠀❍ Breadth = 1.66cm

⠀

• Finding Perimeter

$\: \: \: \: \boxed{\tt{\bigstar{Perimeter_{(Rectangle)} = 2(l + b){\bigstar}}}}$

⠀

$\tt:\implies\: \: \: \: \: \: \: \: {Perimeter = 2(15 + 1.66)}$

⠀

$\tt:\implies\: \: \: \: \: \: \: \: {Perimeter = 2 \times 16.66}$

⠀

$\bf:\implies\: \: \: \: \: \: \: \: {Perimeter = 33.32cm}$

⠀

Hence,

⠀⠀⠀⠀❍ Perimeter of rectangle is 33.32 cm.

Answer 2

☆ Solution ☆

Given :-

• The area of rectangle is 25 cm.
• Length is 15 cm.

To Find :-

• breath and perimeter.

Step-by-Step-Explaination :-

As we know that :-

Area of rectangle = l × b

Let the breadth of rectangle be b.

Putting the respective value

Area of rectangle = 25

Area of rectangle = 15 × b = 25

Area of rectangle = b = 25/15

Area of rectangle = b = 5/3

Area of rectangle = b = 1.66 cm

Hence,

Breadth of the rectangle = 1.66 cm .

Now,

Finding the perimeter of rectangle .

As we know that :-

Perimeter of rectangle = 2 ( l + b )

Pitting the respective value,

Perimeter of rectangle = 2 ( 15 + 1.66 )

Perimeter of rectangle = 2 × 16.66

Perimeter of rectangle = 33.32cm

Hence ,

The perimeter of rectangle = 33.32 cm.
