Question

19) A rectangular field is 54 m long and 40
m wide. Find its perimeter.

please tell answer with step by step...​

Answer 1

Perimeter of rectangle = l*b
=54*40
=2160m

Answer 2

$\huge \sf \underline \red{Answer : }$

$\sf \underline{perimeter = 188m}$

$\huge \sf \underline \blue{To \: find : }$

• Perimeter

$\huge \sf \underline \orange{solution : }$

$\sf \red{Given}\begin{cases}&\sf{Length \: of \: rectangle \: is \: \: 54m} \\ \\ &\sf{width \: (breadth)\: of \: rectangle \: is \: 40m} \\ \end{cases}$

$\sf \underline{we \: know \: that \: perimeter \: formula : }$

$\: \: \: \: \: \: \: \: \: \: \: \: \sf{ \boxed{ \underline{ \underline{ \blue{ \tt{perimeter = 2(l + b)m \: }}}}}}$

• L is 54m

• B is 40m

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf \implies{2(54 + 40)m}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf \implies{2(94)m}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf \implies{188m}$

$\sf \underline{ \therefore \: perimeter = 188m}$
