Answer:
The midpoint is (-4.5,.5)
Step-by-step explanation:
To find the x coordinate, add the x coordinate of the ends and divide by 2
(-1+-8)/2 = -9/2 = -4.5
To find the y coordinate, add the y coordinate of the ends and divide by 2
(5+-4)/2 = 1/2 =.5
The midpoint is (-4.5,.5)

Answer:
Step-by-step explanation:
Rectangle:
length = l = 12 cm
Width = w = 0.8 cm
Use Pythagorean theorem to find the diagonal
Diagonal² = l² + w²
= 12² + 0.8²
= 144 + 0.64
= 144.64
Diagonal = √144.64 = 12.03 cm
Diagonal of square = diagonal of rectangle
= 12.03 cm
To find the side of square again use Pythagorean theorem,
side² + side² = 12.03²
2 sides² = 144.64
side² = 144.64/2
side² = 72.32
side = √72.32
Side = 8.50 cm
