Answer»

Given

Perimeter of a Rectangle is 260cm

length is 30 m more than its breadth

To Find

Length of the Rectangle

$\sf\huge\bold{\underline{\underline{{Solution}}}}$

Let us assume that the breadth be 'x' cm

According to the QUESTION:-

Length is 30 m more than its breadth

=>30+x

Now length is 30+x and breadth is x

Perimeter of Rectangle=2(length+breadth)

Perimeter of Rectangle=2(30+x+x)

=>260=2(30+2x)

=>260=60+4x

=>260-60=4x

=>200=4x

x=200÷4

x=50

Breadth is 50 cm

length is 30+x =30+50=80cm

Check:

Perimeter of Rectangle=2(50+80)

Perimeter of Rectangle=2(130)

Perimeter of Rectangle=260cm

Extra information=>

PERIMETER

Perimeter is the total distance occupy by a solid 2D figure around its edge.

Example in Real LIFE : To fence a field with wire we NEED to find the cost of fencing in such CASE perimeter will used because we have to only fence BORDER of the field.
