Division:-

The expression in company B represents that is is in arithmetic progression where first term is 42000 and common difference is 1800 . So we have to use the formula of sum of n terms which is

Where a is the first term, n is the nth term, d is the common difference
On substituting there values,we will get

= 15(84000+52200) = 15*136200 =2043000
And for company A, it is

Difference between them =2043000-2002500= 40500
So the correct option is the second option .
Answer:
Step-by-step explanation:
l = 7 in
w = 11 in
h = 5 in
Surface area = 2*(lw +wh +hl)
= 2*(7*11 + 11*5 + 5*7)
= 2* (77+ 55 + 35)
= 2 * 167
= 334 square inches
