Answer:

the answer according to my calculations will be 12

Step-by-step explanation:

the formula of area of trapezium is A=a+b÷2×h

and if we wanna solve for h

h=2 A÷ a+b

h=2 (234)÷39

after calculations...

h= 12  

hope it helps:)

Answer:

h = 12 cm

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h ( sum of parallel bases )

Here A = 234 and sum of bases = 39 , then

[tex]\frac{1}{2}[/tex] h × 39 = 234 ( divide both sides by 39 )

[tex]\frac{1}{2}[/tex] h = 6 ( multiply both sides by 2 to clear the fraction )

h = 12
