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

I got 5ft
Step-by-step explanation:
2ft+2ft+1ft=5ft
Hello!
Y2-y1/x2-x1
1-9/8-6
-8/2
The slope is -4
Hope this helps!

1/9 because i you plug in two of the points into y2 -y1 over x2 -x1 thats what you get.
Answer:
y = 1/7x + 88/7
Step-by-step explanation:
y = mx +b
since it is perpendicular you have to get the negative reciprocal of the slope which is 1/7
y = 1/7x + b then you would plug in your points
12 = 1/7(-4) + b and then solve for b
12 = -4/7 + b
+ 4/7
88/7 = b
y = 1/7x + 88/7
