Question

if the perimeter of a rectangle is 100 cm and its length is 20 CM more than its breadth, find its length and breadth.


please help

Answer 1

Hlo friend.. Cutiepie Here..

Here is ur answer :

Let the breadth be x cm

So length be 20 + x cm

Given, Perimeter of Rectangle = 100 cm

A. T. Q.

2 ( Length + breadth ) = 100

2 ( 20 +x + x ) = 100

20 + 2x = 100/2

20 + 2x = 50

2x = 50 - 20

2x = 30

x = 30/2 = 15

Breadth = 15

Length = 20 + 15 = 35

HOPE IT HELPS YOU..

Answer 2

Perimeter of the rectangle= 100cm
Breadth= x
Length= 20+x
Perimeter of the rectangle= 2(l+b)
100= 2(x+20+x)
100= 2( 2x+20)
100= 4x+40
100-40= 4x
60=4x
60/4=x
15=x
Breadth= x
= 15
Length is= x+20
= 15+20
= 35
Hope this helps:-)
