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.
