Also, this is 5 points.
Answer: 37 you just add the two in that case
The perimeter is the sum of the side lengths of a shape. <span> A </span>diagonal is a line segment joining two vertices of a polygon or polyhedron <span>when those vertices are not on the same edge. We calculate as follows:
Perimeter = 4a
560 = 4a
a = 140 meters
</span>A=(1/2)d√(4a^2 - d^2)
A = 10240.56 m^2
2(x + 3) = 18
2x + 6 = 18
- 6 =
2x = 12
Divide 2
x = 6
