Question

Please answer with the correct explanation.

Answer 1

Answer:

I'm not sure but I think its 6 ft because the figure is not a trapezoid, it's a mixture of triangle and trapezium so

Step-by-step explanation:

first we will take out the area of triangle frm the total area given

here ,

area of ️ = 1/2 x b x h

= 1/2 x 12 x 9

= 54

now ,

area of trapezium = area of the composit shape - area of ️

= 108 - 54

= 54

therefore ,

area of trapezium = 1/2 x sum of parallel sides x h

54 = 1/2 x 6+12 x h

54 × 2× 1/18 = h

6 ft = h

done
