Question

the lengthof a rectrangle is 6m less than twice its breath .if the perimeterof the rectrangle is 54 m. find its length and breath

Answer 1

b = x    ,    l = 2x-6            p=2(l+b)       54/2=3x-6         27+6=3x     33/3=x     x=11

Answer 2

let the breadth of rectangle be x

length=2x-6

ATQ
2(l +b)=54
l+b=27
2x-6+x=27
3x=33
x=11 m = breadth
length=2x-6=16m
