Pyramid Surface Area = (½ * Perimeter of Base * Slant Height) + Base Area
Base perimeter = 4 * 18 = 72 inches
Base Area = 18*18 = 324 square inches
Pyramid Surface Area = (.5 * 72 * 12) + 324
Pyramid Surface Area = 432 + 324
Pyramid Surface Area = 756 square inches

and surely you know how much that is.
Answer:
120 m 2
Step-by-step explanation:
37.5 * 6.4 / 2 = 120 m 2
Hey there! :D
First, find the slope.
m= (y2-y1)/(x2-x1) I'm using points (0,3) and (1,5)
m=(5-3)/(1-0)
m= 2/1
m=2
Now, plug that into point slope. Use point (1,5) m=2
y-y1= m(x-x1)
y-5= 2(x-1)
Distribute.
y-5=2x-2
Add 5 to both sides.
y=2x+3 == equation of the line in slope intercept form. y=mx+b
I hope this helps!
