a² - b² = (a + b)(a - b)

Step-by-step explanation:

The side of the outer square is a. Its area is a².

The side of the inner square is b. Its area is b².

The area of the orange section is the difference of the area of the two squares.

A = a² - b²

The area is the difference of two squares which factors into the product of a sum and a difference.

Factor the area:

a² - b² = (a + b)(a - b)

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
