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:

Answer:
8.26
Step-by-step explanation:
you can solve this by putting x for blank
x-5.27=2.99
solve for x
x-5.27+5.27=2.99+5.27
x=8.26
The equation would be y=32x+550. 32 an hour is represented by 32x since she earned 32 an hour. 550 is the extra amount she is getting paid.
I hope this helps.
