Question

What is the area of the triangle in this coordinate plane?

17.5 units²
21.0 units²
35.5 units²
49.0 units²

Answer 1

The base of the triangle starts horizontally from 0 to 7b = 7 - 0b = 7
The height of the triangle start vertically from 1 to 15h = 15 - 1h = 14
Calculate the areaa = 1/2 × b × ha = 1/2 × 7 × 14a = 1/2 × 98a = 49
The area of the triangle is 49.0 units²

Answer 2

base 0 to 7b = 7 - 0b = 7
hight 1 to 15h = 15 - 1h = 14
Calculating the area  it would = 1/2 × b × ha = 1/2 × 7 × 14a = 1/2 × 98a = 49
so The area of the triangle is 49 units² and cense the answers here are as decimals so The area of the triangle is 49.0 units²
