• 2) 1000 tablets.
• 2) $105.35

How to get the area of a rectangle?

For a rectangle of length L and width W, the area is:

A = L*W

In this case we have:

L = 41m

W = 18m

A = 41m*18m = 738 m^2

How many tablets can be made?

We can rewrite:

0.5kg = 500g

And we know that 5mg = 5*10^-3 g

To get the number of tablets we take the quotient between these two numbers:

N = (500g)/(5*10^-3 g) = 1000

You can make 1000 tablets.

How much money did Mr. Verma spent?

He spent $60.20 for the biscuits and 3/4 of that for the toffees, so the total amount that he spends is:

$60.20*(1 + 3/4) = $105.35
