The area of the trapezoid is
[tex]S=\frac{h(a+b)}{2}[/tex]
1) [tex]S=\frac{7(6,2+3,8)}{2} =\frac{70}{2} =35ft^2[/tex]
Answer: S=35ft²
2) [tex]S=\frac{12,6(10,3+15,1)}{2} =\frac{320,04}{2} =160,02in^2[/tex]
Answer: S=160,02in²
3) [tex]S=\frac{8,9(4,4+5,7)}{2} =\frac{89,89}{2} =44,945yd^2[/tex]
Answer: S=44,945yd²
