The formula of an area of a rectangle:
l - lenght
w - width
We have l = 3w and the perimeter P = 256 in. Substitute:
<em>divide both sides by 2</em>
<em>divide both sides by 4</em>
Calculate the area of a rectangle:
The triangle ABC is the half of the rectangle. Therefore the area of a triangle ABC is:
Answer:
See below
Step-by-step explanation:
