1. Construct a circle of arbitrary radius (r₁) with center at point P (blue circle)
2. Mark the points of intersection of the circle with the line AB (points E and D)
3. Construct two circles of identical radii (r₂) with centers at points E and D (green and red circles). Notice: r₂ > r₁
4. Draw a segment through the intersection points of the green and red circles.
60x20=1200
1200/300=4
4x1/2=4/2=2 pounds of grass seed
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:
Step-by-step explanation:
Formulae used:
cos (180°-θ) = -cos θ
sin (80°-θ) = sin θ
Therefore,
