Each blade on a windmill is in the shape of a triangle with a base of 7 feet and a height of 4 ft if there are four blades on the windmill what is the total area of the blades

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:

The total area of the blades is:

5/6
