Answer:
Height of the trapezium shaped lid is=6 inches
Step-by-step explanation:
Area of trapezium=1/2(a+b)h
Here We Have:
Area of Trapezium=36 Square inches
a=5 inches
b=7 inches
height=x
Using trapezium's formula and inserting the values:
36=1/2(5+7)x
36=1/2(12)x
36=1/2*12*x
36=6*x
36/6=x
6=x
Height of the trapezium shaped lid is=6 inches
