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

1. You have that:

- Each blade on a windmill is in the shape of a triangle.

- The triangle has the following dimensions: the base is 7 feet and the height is 4 feet.

- There are four blazer on the windmill.

2. Then, to solve this problem, you must apply the formula for calculate the area of a triangle, which is:

A=bxh/2

b is the base of the triangle (b=7 feet)

h is the height of the trianlge (h=4 feet)

3. Therefore, you have:

A=bxh/2

A = (7 feet) (4 feet) / 2

A=28 feet²/2

A=14 feet²

4. The total area is:

At=Ax4

At = (14 feet²) (4)

At=56 feet²
