ANSWER: 182 inches
STEP-BY-STEP EXPLANATION:
Since, it is an isosceles trapezoid, then area of an isosceles triangle is given by: [tex]\frac{1 (a+b)}{2}[/tex] × h
where a and b are the two parallel sides of the triangle and h is the height of an isosceles triangle.
Now, a= 12 inches and b= 2+2+12=16 inches and h=13 inches.
[tex]\frac{1 (12+16)}{2}[/tex] × 13 = 182 inches
