The mean is
Answer:
(0,0), (-8,-8), (4,-8)
Step-by-step explanation:
(0 * 0, 0*0) = (0,0)
(-4*2,-4*2) = (-8,-8)
(2*2,-4*2) = (4,-8)

Answer:
8units²
Step-by-step explanation:
Area of the trapezoid = 1/2(a+b)h
a and b are the opposite sides
h is the height
Take a square as 1 unit
a = 1 unit
b = 3 units
height h = 4 units
Substitute
A = 1/2(1+3)*4
A = 1/2 * 4 * 4
A = 16/2
A = 8units²
Hence the area of the trapezoid is 8units²
