Question

the perimeter of rectangle is 50m. the length of the rectangle is 4m less than 5 times its breadth find the breadth of the rectangle​

Answer 1

Answer:

let perimeter of the rectangle = 50 m

let breadth = x

length= 5x-4m

perimeter= 2(a+b)

50=2(5x-4+x)

50=2(6x+4)

50=12x-8

50-8=12x

42=12x

x=42/12

x=3.5m

Answer 2

Step-by-step explanation:

$\huge\blue{\boxed{\fcolorbox{red}{purple}{Answer;-}}}$

the perimeter of rectangle is 50m

Let,

the breath =xm

then ,

the length=5x-4m

the formula is

$\large{\boxed{\blue{perimeter=2(a+b)}}}$

according to formula

50=2(5x-4+x)

=>50=2(6x-4)

=>50=12x-8

=>50+8=12x

=>12x=58

=>x=58/12

=4.8m

the breadth=4.8cm

length=5(4.8)-4

=24-4

=20m

Hence the breadth of rectangle is 4.8m
