Answer 1

well do you know how to find the area of a trapezoid? you could use that formula to solve for the height (h)

Answer 2

No i dont, I think i do a=l*w

Answer 3

But we dont know the length

Answer 4

no... that'd be for a square or rectangle.. the area for a trapezoid is \[A=\frac{ a+b }{ 2 }h\]

Answer 5

hmm whats the base for this one then

Answer 6

80?

Answer 7

yea... a+b=80 in this case...

Answer 8

ok

Answer 9

I think you guys mixed up the formulas....

Answer 10

so you have \[108=\frac{ 80 }{ 2 }h\]

Answer 11

how so?

Answer 12

\[h=2\frac{ A }{ a+b }\]

Answer 13

That formula you gave is for Area not height

Answer 14

I know... I was just going to solve the formula for height...

Answer 15

\[h=2\frac{ 180 }{ 8+10 }\]

Answer 16

The area formula was unecessary it would confuse them :)

Answer 17

@CREEPYMLPMASTER can you solve that?

Answer 18

10?

Answer 19

u calculated wrong
