The total area of the blades is the area of a triangle multiplied by 4.
We have then:

Where,
b: base of the blades
h: height of the blades
Substituting values we have:

Doing the calculation we have that the area of the blades is given by:

Answer:
The total area of the blades is:

Taylor will earn $21 more in compounded interest than in simple interest.
Given:
Principal = 2100
interest rate = 1.85%
term = 8 years
Simple Interest = Principal * interest rate * term
= 2100 * 1.85% * 8
= 310.80
Compounded Interest = Principal * (1+r)^t
= 2100 * 1.0185⁸
= 2100 * 1.158
= 2431.80
Interest from Compounded Interest : 2431.80 - 2100 = 331.80
Simple Interest = 310.80
Compounded Interest = 331.80
331.80 - 310.80 = 21
