Question

AREA OF TRAPEZOID TWER?

Answer 1

a=1/2(b1+b2)xh

Answer 2

a=1/2(9+21)x8

Answer 3

we just did this

Answer 4

I did 9+21= 30, then do 30 x 8= 240 divided by 2=

Answer 5

120?

Answer 6

\[A={1\over2}h(b_1+b_2)\]\[A={1\over2}(8)(9+21)\]yes it is 120 :)

Answer 7

than you!!!

Answer 8

what about this one?

Answer 9

post it as a new question :)

Answer 10

same thing right
?

Answer 11

if it asks for the area of a trapezoid use the formula \(A={1\over2}h(b_1+b_2)\)
