b1=140b2=155h=190
The area of a trapezoid is equal to 12 times the height times the sum of the bases b1+b2.
12⋅(height)⋅(b1+b2)
Substitute the values of the height h=190 and bases (b1=140 and b2=155) into the formula for the area of a trapezoid.
12⋅190⋅(140+155)
Factor 2 out of 190.
12⋅(2(95))⋅(140+155)
Cancel the common factor.
12⋅(2⋅95)⋅(140+155)
Rewrite the expression.
95⋅(140+155)
95⋅(140+155)
Add 140 and 155.
95⋅295
Multiply 95 by 295.
