Know the difference of what?
Answer:
the formula of a trapezoid is
H(a+b/2)
A= side 1 (usually the two parallel sides, choose one)
b= side 2 (same thing as A but the second line)
The h is height
So we fot 10 and 9
10+9=19
19/2=9.5
9.5*6
57
the Area is 57
Also you drew it wrong (look at image)
A jewelry makes has 24 jade and 30 teak beads.
Find the number of necklace can a jewelry maker make with 24 jade beads and 30 teak beads
=> 8 x 3 = 24
=> 10 x 3 = 30
=> (8 + 10) x 3 = 24 + 30
=> 18 x 3 = 24 + 30
=> 54 + 54
Thus, a jewelry maker can make 3 necklace out of 54 beads.
There will be 8 jade beads in each necklace and 10 teak beads in each necklace. Hope that helps!
