Answer: (a,b)= (7.13 ,-8.27)
Step-by-step explanation:
From the data, we have
A-B+3C=0
where, A= (-8.6, 18.0)
B= (12.8, -6.8)
and let C= (a, b)
So, putting values
(-8.6, 18.0) - (12.8, -6.8) + 3(a,b)=0
3(a,b) + (-21.4, 24.8) = 0
3(a,b)= (21.4, -24.8)
(a,b)= (7.13 ,-8.27)
The area of the shaded part is: 42.14 ft² .
<h3>Area of Square</h3>
Area = s²
<h3>Area of Quarter Circle </h3>
Area = 1/4πr²
Thus:
Area of the shaded part of the figure = area of square - area of quarter circle
Area of shaded part = s² - 1/4πr²
s = 14 ft
r = 14 ft
Substitute
Area of shaded part = 14² - 1/4(3.14)(14²)
= 42.14 ft²
Therefore, the area of the shaded part is: 42.14 ft² .
