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 

What’s the question?
