Answer:
Area = 20 units²
Step-by-step explanation:
<em>Let A(-8,-2), B(-3,-2), C(-3,-6) and D(-8,-6) so that the rectangle becomes ABCD.</em>
=> <u><em>Since it's a rectangle it will have two opposite sides equal.</em></u>
<em>So, let's find the length of any two sides (as length and width) by Distance Formula.</em>
Distance Formula =
<u><em>Side AB:</em></u>
|AB| =
|AB| =
|AB| = 5
<u><em>Side BC:</em></u>
|BC| =
|BC| =
|BC| = 4
<u><em>Now, Area:</em></u>
Area of the rectangle = Length * Width
Area = 4 * 5
Area = 20 units²
