Answer:
Perimeter: 6+[tex]9\sqrt{2}[/tex] units
Area: 13.5 [tex]units^{2}[/tex]
Step-by-step explanation:
I wasn't sure what to estimate to...
for perimeter use: [tex]a^{2} +b^{2} =c^{2}[/tex]
I noticed that the trapezoid was made up of 3 identical triangles, so find the area of one of them times 3
one triangle area: [tex]\frac{1}{2}[/tex] (b · h) b = base, h = height
plug- in values, so [tex]\frac{1}{2}[/tex] (3 · 3) is half of 9 which is 4.5.
3 · 4.5 is 13.5
