Let the breadth of the Rectangle be$\bold{\red{ 'x'm}}$

then ,length of the Rectangle be$\bold{\red{ 3x}}$

Given : Perimeter of the field is 300m

Formula:

$\bold{\boxed{Perimeter \:of \:rectangle = 2(l + b)}}$

$= > 300 = 2(3x + x)$

$= > 300 = 8x$

$= > 8x = 300$

$= > x = \frac{300}{8} = 37.5$

Hence,breadth of the Rectangle is $\bold{\red{37.5m}}$

Length of the Rectangle is 3x=3×37.5=$\bold{\red{112.5m}}$

let's check by putting values in the formula:

$\bold{= > 2(l + b) = 300}$

$\bold{= > 2(112.5 + 37.5) = 300}$

$\bold{= > 2(150) = 300}$

$\bold{= > 300 = 300}$

$\bold{\boxed{Area \:of\: rectangle = l \times b}}$

$\bold{\boxed{Area \:of\: square = {(side)}^{2}}}$

$\bold{\boxed{Area\: of\: triangle = \frac{1}{2} base \times height}}$

$\bold{\boxed{Area \:of \:circle = \pi {r}^{2} }}$
