Answer:
Perimeter: 18.5
Area: 15
Step-by-step explanation:
P = a + b + c
P = 5 + 6 + 7.5
P= 18.5
A = 1/2bh
A = 1/2*7.5*4
A= 15
For a segment AB, the coordinates of the middle point C are:
xc=(xa+xb)/2,
yc=(ya+yb)/2.
Now, you know points A and C. Thus we get:
xb=2×xc-xa
yb=2×yc-ya
With numerical values:
xb=2×2-(-1)=4+1=5
yb=2×3-(-5)=6+5=11
Answer: B(5, 11)
