1. Problem Description
The problem asks us to find the area of an arrow-shaped figure plotted on a coordinate plane. The vertices of the figure are given as (-2, 2), (5, 2), (5, 6), (12,0), (5, -6), (5, -2), and (-2, -2).
2. Solution Steps
We can divide the arrow into a rectangle and a triangle.
The rectangle has vertices (-2, 2), (5, 2), (5, -2), and (-2, -2).
The length of the rectangle is .
The width of the rectangle is .
The area of the rectangle is .
The triangle has vertices (5, 6), (12, 0), and (5, -6).
The base of the triangle is the vertical distance between (5, 6) and (5, -6), which is .
The height of the triangle is the horizontal distance between (12, 0) and (5, 0), which is .
The area of the triangle is .
The area of the arrow is the sum of the areas of the rectangle and the triangle.
Area of arrow = Area of rectangle + Area of triangle = .
