Question

the area of a rectangular plot is 540 metre square. if uta length is 27 metre , find its breadth and perimetre.​

Answer 1

Answer:

Area of rectangle = l×b= 540

Length of rectangle = 27 m

Breath = 540÷27

= 20m

perimeter = 2(l+b)

= 2 (20+27)

= 2×47

= 94m²

Answer 2

Question:-

• The area of a rectangular plot is 540 m².If the length is 27 metre,find its breadth and perimeter.

To Find:-

• Find its breadth and perimeter.

Given:-

• The area of a rectangular plot is 540 m².If the length is 27 m.

Solution:-

$\tt\implies \: Area of Rectangle = l × b$

$\tt\implies \: 540 = 27 × b$

$\tt\implies \: b = \cancel\dfrac { 540 } { 27 }$

$\tt\implies \: b = 20 m$

Now ,

$\tt\implies \: Perimeter of Rectangle = 2( l + b )$

$\tt\implies \: Perimeter = 2( 27 + 20 )$

$\tt\implies \: Perimeter = 2( 47 )$

$\tt\implies \: Perimeter = 94$

Hence ,

• Breadth is 20 m.

• Perimeter is 94 $\tt \: { m }^{ 2 }$
