Answer:
80
Step-by-step explanation:
The area of a trapezoid is calculated by dividing sum of bases and that multiplied by height
(a+b)/2 × h (a : base, b: base, h: height)
the bases given here are 3 and 17 and height is 8
(17+3) ÷ 2 × 8 = 80
7+7+3=17 (Base 1)
(17+3(Base 2) ÷ 2= 10
10 x 8 (Height) =80
