Question

The length of a rectangle is 10 cm more than its breadth. If the perimeter of the rectangle is 30 cm. Find the length and breadth of the rectangle.

Please answer correctly.​

Answer 1

Answer:

Step-by-step explanation:

L=B+10

P=2*[B+10+B]

30=2B+20+2B

30=4B+20

30-20=4B

10/4=B

2.5=B

L=B+10

 =2.5+10

 =12.5

LENGTH=12.5

BREADTH=2.5

Answer 2

Step-by-step explanation:

let length and breadth be x

length= x+10 and breadth=x

A/Q

perimeter = 2(l+b)

30= 2(x+10+x)

30=2(2x+10)

30=4x+20

30-20 = 4x

10 = 4x

X= 10/4

X =5/2

Now,

length= x+10

= 5/2+10

= 25/2

breadth= 5/2
