A triangle has base 15 feet (ft) and an altitude of 4 ft. Find its area
The formula for the area of a triangle is 1/2 the base times the altitude (height):
A = 1/2bh
A = 1/2 * 15 * 4
A = ?? sq. ft.
A=30?
Right. A = 30 sq. ft.
To find the area of a triangle, you can use the formula:
Area = (base * altitude) / 2
In this case, the base of the triangle is 15 ft and the altitude is 4 ft. Let's plug these values into the formula:
Area = (15 ft * 4 ft) / 2
Now, let's calculate the area:
Area = (60 ft²) / 2
Area = 30 ft²
Therefore, the area of the triangle is 30 square feet.
