3.2-5.7=-2.5 so its have to be a negative because a smaller number subtract a bigger number have to be equal to a negative number.
Pls put photo so that I can do the equation.
The answer to this question is -8
Trapezoid Area =
[ ( Sum of the rules ) × ( height ) ] ÷ 2
_________________________________
Area = [ ( 6 + 12 ) × 8 ] ÷ 2
Area = [ 18 × 8 ] ÷ 2
Area = ( 18/2 ) × 8
Area = 9 × 8
Area = 72
