Alex wants to paint one side of his skateboard ramp with glow-in-the-dark paint, but he needs to know how much area he is painting. Calculate the area of the isosceles trapezoid.
|dw:1434046250486:dw|This is it (:
I believe the answer is 112 but i need to be sure of it.
hm, not quite, can you show me your math?
its multiple choice here are the answers 112 ft2 128 ft2 132 ft2 144 ft2
can you show me how you got the answer 112?
i want to make sure you aren't just guessing, ok? :)
1. do base times hight which is 8 times 18 2. you have your answer I think thats how you do it
previous answer is incorrect
Mahmood's answer is incorrect, please show me how you got your answer
but you see what @Vocaloid has to say
base times hight 8 times 18 144
thats what my school taught me how to do it
nope, this is a trapezoid, not a rectangle to find the area of the trapezoid, use the formula A = height*(base1+base2)/2
oops wrong formula
i did 18 x 8
not quite, that would be a rectangle, not a trapezoid
to find the area of a trapezoid: take the top part (14), add the bottom part (18), then divide by 2 then multiply by the height (8)
not quite... let's break it down step by step: what is (14+18)/2?
great, so what is 16*8?
excellent! that's the area of the trapezoid! remember: to find the area of a trapezoid, add the two bases together, divide by 2, then multiply by the height
(: thank you so much
can you help with more?
I guess, sure
ok im going to make new question so i can give you more medals if you help
sure, just tag me when you're done
