There are four triangles and one square, the areas of which can be added together to form the total surface area.
Area of triangle = 0.5bh
= 0.5*16*15
= 120 cm^2
Since there are four triangles, the total area for them would be 120*4 = 480 cm^2
Area of square = 16^2 = 256
Total surface area = 256 + 480 = 736 cm^2
Lines that are parallel have the same slope, and I'm going to guess you meant y= 1/2x + 8.
So already starting we know the other equation is y= 1/2x + b. But now we have to find b.
We do this by plugging in the coordinate given.
2=1/2(-2) + b
2= -1 + b
3 = b
This means the equation you want is y= 1/2x + 3.
I hope this helps!
Answer: 10y
Step-by-step explanation: All variables equal one unless assigned a specific answer. So It is basically 9y+1
9y+1=10y
Final Answer: 10y
