Question

polygon on the coordinate plane. 6. w(-4,4) x(2,4) z(-4,1) y(2,1) p = ______ a = ______

Explanation:

Step1: Find side - lengths

For horizontal side between $Z(- 4,1)$ and $Y(2,1)$, length $l_1=\vert2 - (-4)\vert = 6$. For vertical side between $Y(2,1)$ and $X(2,4)$, length $l_2=\vert4 - 1\vert = 3$.

Step2: Calculate perimeter

$P = 2(l_1 + l_2)=2(6 + 3)=18$.

Step3: Calculate area

$A=l_1\times l_2=6\times3 = 18$.

Answer:

$P = 18$
$A = 18$
