Question

the length of a rectangle is 2 cm more than 4 times its breadth its perimeter is 54 what is length​

Answer 1

Answer:

The answer is 5 cm

Step-by-step explanation:

Let the breadth be x

Then, the length will be= 4x+2cm

Perimeter= 2(length+breadth)

2(x+4x+2)=54

2(5x+2)=54

10x+4=54

10x=54-4

10x=50

x=50/10

x=5

Length is 5 cm and breadth is 4×5+2=22

Hope it helps.....

Answer 2

Answer:

Let it's breadth be B and length L.

It is given L=2+4B

perimeter=2(L+B)=2(2+4B+B)=54

2(2+5B)=54

2+5B=27

5B=27-2=25

B=25/5=5

L=2+4B=2+20=20 Ans
