Question

How many rectangles can be drawn with 38cm as perimeter also find dimensions of the rectangle whose area will be greatest

Answer 1

Answer:

There are 9 rectangles.

Step-by-step explanation:

Perimeter = 38

38 = 2 × ( l + b )

38 / 2 = ( l + b )

19 = ( l + b )

possible dimensions are :-

( 1 + 18 ) , ( 2 + 17 ) , ( 3 + 16 ) , ( 4 + 15 ) , ( 5 + 14 ) , ( 6 + 13 ) , ( 7 + 12 ) ,

( 8 + 11 ) , ( 9 + 10 )

Thus , there are 9 rectangles.
