Answer:
The first option:
[tex]Area = 27units^{2} \\Perimeter = 26 units[/tex]
Step-by-step explanation:
The area of a trapezoid can be found by using the following formula where "a" and "b" are the bases and "h" is the height of the trapezoid.
[tex]Area = \frac{(a +b)h}{2} = \frac{3(7 + 11)}{2} = \frac{3(18)}{2} = \frac{54}{2} = 27 units^{2}[/tex]
The perimeter can be found by adding the lengths of all sides. Therefore the perimeter of this trapezoid equals...
Perimeter = 3 + 11 + 5 + 7 = 26 units
