The midpoint of segment QR is M(-2, 9). One end point of segment QR is Q(-8, 12). Find the coordinates of the other endpoint, R.

DanielleElmas [232]

Here,

The midpoint of segment QR is M

m(-2,9) x3=-2,y3=9

Q=(-8,12)x1=-8,y1=12

R=x2,y2

we know that,

$\tt{ m=\dfrac{Q+R}{2} }$ ⠀

So,

x3= $\tt{\dfrac{x1+x2}{2} }$ ⠀

$\tt{-2=\dfrac{-8+x2}{2} }$ ⠀

$\tt{-2×2=-8+x2 }$ ⠀

$\tt{x2=8-4 }$ ⠀

$\tt{x2=4 }$ ⠀

x2=4

now we find the y coordinate y2.

y3= $\tt{\dfrac{y1+y2}{2} }$ ⠀

$\tt{9=\dfrac{12+y2}{2} }$ ⠀

$\tt{9×2=12+y2 }$ ⠀

$\tt{y2=18-12 }$ ⠀

$\tt{y2=6 }$ ⠀

y2=6

Now we get the two coordinate of R

so,

R=(x2,y2)=(4,6)

Answer:

224 cm²

Step-by-step explanation:

Look at the figure below.

All sides are in cm. All areas are in cm².

Triangle A:

A = bh/2 = 8 × 21 / 2 = 84

Rectangle B:

A = LW = 9 × 8 = 72

Rectangle C:

A = LW = 4 × 5 = 20

Triangle D:

A = bh/2 = 6 × 16 / 2 = 48

Total area = 84 + 72 + 20 + 48 = 224

Answer: 224 cm²
