Where
b is the width of the rectangle and 
is the length
Then the area of the rectangle is:
Finally the total area is:
Yes because all equilateral triangles have equal angles and side lengths so they are all similar. hope i helped -J
We use the fact that x2+y2=1 This is the equation of the unit circle.
We know that x=-4/5, so plug this in and solve for y
x2+y2=1 <span>(−4/5)^2+y2=1</span> 16/25+y2=1 y2=1−16/25 y2=9/25 <span>y=−square root of 9/ 25</span>
y = -3/5
