if a 36 cm thread is used to wrap a book , lengthwise twice and breadthwise once, what is the size..

Answer / n

@ Aprameya Shyam
length=x does not imply breadth=36-x

2x+4y=36.

3 possible answers are
(2,8) -> 16sqcm.
(4,7) -> 28sqcm.
(6,6) -> 36sqcm

Answer / sharif m

length of the book = x
width of a book = y

4x + 2y = 36
(one wrap covers both side length of the book same in width
also - so two wrap covers 4x as well as in 2y)

4(6)+ 2(6)=36
4(7)+2(4) =36
4(8)+2(2)=36

are the possible roots.... second shud be the answer
because that parameters are ideal for a book.

7 x 4 is the size of book

Answer / poornima

length of the thread is 36. length wise twice breath wise
once thn totally thrice. so 36/3=12. so length is 12*2=24
breath is 12. area=length * breath=24*12=288sq.cm

Answer / geo

length=x does not imply breadth=36-x
given that thread cover length is twice and breadth once
once a book covered by length means twice the length is covered
so if twice length is covered then 4*length is covered
likewise consider breadth

4x+2y=36.

so u can give some random values to x and y
some possible set for x and y are
(8,2),(7,4),(6,6)

(6,6) -> 36sqcm

Answer / aprameya shyam

let length=x... then breadth=(36-x)
since thread is used lengthwise twice & brdthwise once v
can write 4x + 2(36 - x) = 36 cm
bcoz there are 2 lengths n two 2 in a 4 sided figure(dis is
obvious)

solving v get x=-18 (ignore the -ve sign)

hence l = 36-18 = 18 & b = 18

so area=l*b = 18 * 18 = 324sqcm
