They are perpendicular because when you change 2x+8y=16 to slope intercept form it becomes y= -1/4x+2 and the slope (-1/4) is the negative reciprocal of 4, which is the slope for your other equation.

Answer:
13.76 square meters
Step-by-step explanation:
The side of square is 8 meters.
So, the diameter of circle = 8 meters.
⇒ Radius = (diameter of circle) ÷ 2 = 8 ÷ 2 = 4 meters
Shaded region = Area of square - Area of circle
= (Side × Side) - π × (radius)²
= 8 × 8 - π × 4 × 4 {∵ π = 3.14 or 22÷7}
= 64 - 50.24
= 13.76 square meter
You can form an equation and solve it to find your answer:
(7 - s)/3 = 2
× 3
7 - s = 6
+ s
7 = 6 + s
- 6
s = 1
So your answer is 1, I hope this helps!
