Question

What is the area of a right triangle with vertices of (-2,-4),(2,-4), and (2,5)?

Answer 1

A = 18

Explanation:

The formula for the area of a triangle is

A = ½bh

b = x₂ - x₁ = 2 - (-2) = 2 + 2 = 4

h = y₂ - y₁ = 5 - (-4) = 5 + 4 = 9

A = ½ × 4 × 9 = 18

The area of the triangle is 18.
