Answer:
Step-by-step explanation:
The area of a rectangle is length times width.
We divide the polygon into 4 rectangles:
The area of the first rectangle is :
The area of the second rectangle is
The area of the 3rd rectangle is
The area of the fourth rectangle is
Putting all together, the area of the polygon is;
0.16+1.44+1.6+0.4=3.6m²
Answer:
x ≈ 0.290640965127
Step-by-step explanation:
By subtracting the right side of the equation, we get a function that is zero at a real solution for x. The only x-intercept is at approximately 0.290640965127.
___
The graph shows the x-intercept to be 0.2906. The value above was obtained by Newton's method iteration. The roots of this cubic will all be irrational.
