Question

A rectangular plot is 200sq.mts in area.If its breadth is 10mts, then its perimeters is ?

Answer 1

we know
 area of rectangle=length×breadth
200=length×10
length=200÷10
length=20mts
now
 perimeter of rectangle=2(length+breadth)
                                   =2(20+10)
                                   =2(30)
                                   =60 mtrs

Answer 2

Given:

The area of the rectangle is 200 square meters.

The rectangle has a breadth of 10 meters.

 

To find:

The perimeter of the rectangle.

Solution:

A rectangle is a form of a quadrilateral whose opposite sides are equal.

Let us name the rectangle PQRS.

Let us take the length of the rectangle as L meters.

We know that area of the rectangle PQRS is,

Area = Length × Breadth.

200 = L× 10

L = 200/10

L = 20 meters

The perimeter of the rectangle PQRS is,

Perimeter = 2 × (L + B)

Where L and B are the length and breadth of the rectangle, respectively.

Therefore,

Perimeter = 2 × (20 + 10)

= 2 × (30)

Perimeter = 60 meters

Hence, the perimeter of the rectangle PQRS is 60 meters.
