Solving the above for n

n = (S - P) / (P i)

Given:

S=3P

i = 16% = .16

then

n = (3P - P) / (P .16) = 2 /.16 = 12.5

25 cm wide3. What will be the change in the area of a rectangle if(a) length and breadth are doubled?là em

Answer»

ANSWER:

LET length of and breadth of a rectangle are xcm and ycm

⇒ Area of a rectangle =length×breadth

=xy

⇒ Area of a rectangle =xycm² ---- ( 1 )

Now, when length and breadth gets double.

The length and breadth becomes 2x and 2y

⇒ Area of a rectangle =2x×2y

=4xycm²

⇒ Area of a rectangle= 4xycm² --- ( 2 )

Comparing ( 1 ) and ( 2 ) we can see,

⇒ If the length and the breadth of a rectangle are doubled then its area becomes 4 TIMES.
