What is the area of a triangle that has a base of 4 feet and a height of 4 feet? 2ft sq 4ft sq 8ft sq 16ft sq

8ft sq is your area.

Step-by-step explanation:

Solve the area of a triangle by using the following equation:

Area (of a triangle) = 1/2(base * height)

Note:

Height = 4 feet

Base = 4 feet

Plug in the corresponding numbers to the corresponding variables.

Area = 1/2(base * height)

Area = 1/2(4 * 4)

Solve. Follow PEMDAS. First, solve the parenthesis, then divide:

Area = 1/2(4 * 4)

Area = 1/2(16)

Area = 16/2

Area = 8

8ft sq is your area.

Step-by-step explanation:

The area of a triangle can be calculated with the following formula:

Where "b" is the base and "h" is the height of the triangle.

In this case you know that this triangle has a base of 4 feet and a height of 4 feet, then:

Therefore, you can substitute these values into the formula, getting that the area of this triangle is:

Step-by-step explanation:

The fence posts are cylindrical. To determine how much paint is needed to paint the surfaces if each fence post, we need to determine the total surface area of each fence post. The formula for determining the total surface area of a cylinder is expressed as

Total surface area = 2πrh + 2πr²

r and h represents the radius and height of each fence post.

From the information given,

h = 7 feet

Diameter = 1 foot

r = diameter/2 = 1/2 = 0.5 foot

Total surface area = (2 × 3.14 × 0.5 × 7) + (2 × 3.14 × 0.5²)

= 23.55 square feet

Since the number of fence posts is 11, the total amount of paint needed should cover

23.55 × 11 = 259.05 square meters
