Question

Find the area of the following geometric figure.

Find the area of a triangle with base of 15 m and altitude of 12 m.
Area = ___ m^2
Options:
180
27
90

Answer 1

Answer:90

Explanation:

Answer 2

The equation for the equation of a triangle is
`A = (1)/(2) bh`, where A = area of triangle, b = base of triangle, h = height of the triangle.

The altitude is the same as the height of the triangle. That means h = 12. We are also told that the base, b = 15. Plug these numbers into the equation and find A, the area of the triangle:

`A = (1)/(2) bh\\ A = (1)/(2) (15)(12)\\ A = (1)/(2) (180)\\ A = 90 m^(2)`

------

Answer: C)
`90 m^(2)`
