What is the area of a triangle with vertices at (−4, 1), ​(−7, 5)​ , and ​(0, 1)​ ?

Respuesta :

Answer: 8 squared units.

Step-by-step explanation: Let's calculate the width at the bottom and to the height. The width at the bottom of the triangle is 4, since the two points lay on the same x-coordinate and they are 4 units away from one another. Now, let's calculate the height. We do not need to worry about the x-coordinates since they measure the width, so we compare the y-coordinates. 1 subtracted from 5 equals 4. We know that the width is 4 and the height is 4, and we know that the formula of calculating a triangle is width times height divided by 2. 4x4 equals 16, and 16/2 equals 8. Therefore, the area of the triangle is 8 squared units.
