Question

the perimeter of a rectangular plot with length three times the breadth is 2 km what is the length of a plot

Answer 1

Given:-

• Perimeter of the plot = 2km = 2000m

To find:-

• length of the plot
• breadth of the plot

Assumption:-

Let the breadth be x

$\sf{Length = 3 \:times\: breadth = 3 \times x = 4x}$

Solution:-

$\sf{Perimeter\: of\: a\: rectangular\: plot = 2\times(Length + Breadth)}$

= $\sf{2000 = 2\times(x + 3x)}$

= $\sf{\dfrac{2000}{2} = 4x}$

=>$\sf{\dfrac{1000}{4} = x}$

=> $\sf{x = 250}$

Now,

$\sf{Length = 3x}$

= $\sf{3 \times 250\:m}$

= $\sf{750m}$

=>$\sf{\dfrac{750}{1000} \:km}$

=> $\sf{Length = 0.75\:km}$

$\sf{Breadth = x}$

= $\sf{250\:m}$

= $\sf{\dfrac{250}{1000}\:km}$

=>$\sf{0.25\:km}$

Additional Information:-

• $\sf{Perimeter\: of \:a \:rectangle = 2(length + breadth)\:units}$

• $\sf{Perimeter\:of\:a\:square = (4\times side)\:units}$

• $\sf{Area\:of\:a\:rectangle = (length\times breadth) \:sq.units}$

• $\sf{Area\:of\:a\:square = {(side)}^{2} \:sq.units}$
