Question

1. A rectangle has an area of 18 cm2. If its
length and width are whole numbers,
what is its greatest possible perimeter?​

Answer 1

$\large\bf\ ANSWER :- L = 18 , B = 1$

Area = 18 cm²

$\sf\boxed{ Area = L × B }$

L × B = 18

Possible value are tha factors of 18

(1 , 18 ) , (3 , 6) , (2,9)

$\rule{10cm}{0.02cm}$

$\boxed{ perimeter = 2( L + B ) }$

Applying the value here ,

Maximum value is given by ( 1 , 18 )

$\rule{10cm}{0.02cm}$
