A_"Trapezoid"=1/2(b_"1"+b_"2")hATrapezoid=12(b1+b2)h

Explanation:

This is always the formula for solving the area of a trapezoid, where b_"1"b1 is base 1 and b_"2"b2 is base 2.

If we were to solve for the area of this trapezoid, it would be

A=1/2(8+6)4A=12(8+6)4
A=1/2(14)4A=12(14)4
A=7*4A=74
A=28"units"^2A=28units2 Remember that area units are always squared

You may also see it written as

A=(a+b)/2 * hA=a+b2h, which is still the same thing

Sidenote: You may have noticed that the 77 and 55 became negligible when solving the area, as these will never be used for area of a trapezoid.
