Question

1. trapezoid abcd find side lengths first! ab = 3 ad = 5 dc = 6 bc=\sqrt{(-3 + 6)^2+(3 - 8)^2}= bc = 5.8 3+5+6+5.8= perimeter = __ 4. trapezoid efgh area = __

Explanation:

Step1: Recall perimeter formula

The perimeter $P$ of a polygon is the sum of the lengths of its sides. For trapezoid $ABCD$, if the side - lengths are $AB$, $AD$, $DC$, and $BC$, then $P=AB + AD+DC + BC$.

Step2: Substitute given side - lengths

We are given that $AB = 3$, $AD = 5$, $DC = 6$, and $BC=5.8$.
$P=3 + 5+6 + 5.8$

Step3: Calculate the sum

$3+5+6 + 5.8=(3 + 5)+6 + 5.8=8+6 + 5.8=14+5.8 = 19.8$

Answer:

$19.8$
