Area of decagon is given by:
Area=1/2(nsr)
where:
n=number of sides
s=side length
r=height
thus the area will be given by:
Area=1/2(10*4*6.2)
Area=124 cm^2

79,350 cm
Explanation:
115x115=13,225 (this is the area of one side)
13,225x6=79,350(a cube has 6 sides)
Answer:
(-
, 0 )
Step-by-step explanation:
to find where the line crosses the x- axis, let y = 0 in the equation and solve for x
5x - 2(0) + 1 = 0
5x - 0 + 1 = 0
5x + 1 = 0 ( subtract 1 from both sides )
5x = - 1 ( divide both sides by 5 )
x = - 
the line crosses the x- axis at (-
, 0 ) or ( - 0.2, 0 )
No I do not agree with (2,-4) I believe the solution is (-4,2)
