yanalaym [24]

[ Answer ]

$\boxed{\bold{84 \ In.^{2} }}$

[ Explanation ]

Formula For Area Of Trapezoid: $\boxed{\bold{\frac{a \ + \ b}{2}Height }}$

-----------------------------------------

A = 10

B = 18

H = 6

Plug Numbers Into Equation: $\boxed{\bold{\frac{10 \ + \ 18}{2}Height }}$

Solve

10 + 18 = 28

28 ÷ 2 = 14

14 · 6 = 84
