Question

the perimeter of a rectangular plot is 200m. it's length is 4times than its breath of the rectangular plot. find length and breadth of plot?

Answer 1

hey
here is your answer
____________________________________

let the breadth be x
so length=4x

now,
p=2(l+b)

200=2(4x+x)
200=8x+2x
200=10x
x=20

now,
breadth is 20

length is 4×20
= 80

Answer 2

Given that,

Perimeter of rectangular plot = 200m

Let, the measure of Breadth be x

And then,

Let,the measure of Length =4x(length is 4times than of Breadth)

Perimeter = 2 (l+b)

Putting all the above value on Formula....

200m = 2(4x+x)

200m = 8x+2x

200m = 10x

Or,

10x = 200m

x = (200/10) m

x = 20 m

Hence, Breadth = x = 20m

And Length = 4x = 4 x 20 m = 80m
