Question

the length and breadth of a rectangular park are 45 1 by 2 m and 34 3 by 4 m respectively. find the perimeter and area of the park.
​

Answer 1

Answer

$\rm{length \: of \: rectangle = 45 \frac{1}{2} \: m}$

so,

$\rm{length \: = \frac{91}{2} \: m }$

$\rm{breadth \: of \: rectangle = 34 \frac{3}{4} \: m}$

so,

$\rm{breadth = \frac{139}{4} \: m }$

Now

$\boxed{ \red{area \: of \: rectangle = length \times breadth}}$

so,

Area of rectangle = ( 91/2)×(139/4)

Area of rectangle = 12649 / 8 m^2

_________________________

$\boxed{ \red{perimeter of \: rectangle = 2(l + b)}}$

$\tiny{where \: l \: is \: the \: length \: and \: b \: is \: breadth}$

so,

perimeter of rectangle= 2 [(91/2) +(139/4)]

Perimeter of rectangle = 321 / 2 m.
