Answer:
a)
Step-by-step explanation:
To find the length of all three sides, you have to use the Distance Formula:
<em>D</em>[2, 6], and <em>B</em>[−2, 3] → <em>DB</em>
<em>DB</em><em> </em>is 5 units long.
<em>E</em>[3, 2] and <em>B</em>[−2, 3] → <em>EB</em>
<em>EB</em><em> </em>is units long.
<em>E</em>[3, 2] and <em>D</em>[2, 6] → <em>ED</em>
<em>ED</em> is units long.
Altogether, you have the perimeter of units.
