Answer:

The length of the rectangle is 15 cm.

Step-by-step explanation:

breadth(b)=?

length(l)= 3+2b

perimeter(P)= 42 cm

Now,

  P = 2 ( l+b )

or, 42= 2 ( 3+2b+b)

or, 42 = 2 ( 3+3b)

or, \frac{42}{2} = 3+3b

or, 21 = 3+3b

or, 21-3 =3b

or, 18 = 3b

or, \frac{18}{3} = b

or, 6 = b

Here, Breadth(b)= 6 cm

Length (l) = 3 + 2*6

              = 3 + 12

              =15 cm

company A :

30,000 + 0.03(37499) = 31124.97...sales less then 37500

30,000 + 0.03(37501) = 31125.03....sales exceed 37500

30,000 + 0.03(249000) = 37470 ...sales less then 250000

30,000 + 0.03(251000) = 37530....sales exceed 250000


company B :

25,000 + 0.05(37499) = 26874.95...sales less then 37500

25,000 + 0.05(37501) = 26875.05...sales exceed 37500

25000 + 0.05(249000) = 37450...sales less then 250000

25,000 + 0.05(251000) = 37550...sales exceed 250000


so i believe your answer is option b,

company A pays better when sales are less then 250,000, but company B pays better when sales exceed 250,000 <==
