@dude

dude:

First find the area of the trapezoid

Nicole:

I mean thats the only thing I need to do for this question but I need help setting up the equation

dude:

You should have the equation in a formula sheet. You don't have a reference sheet?

Nicole:

I know the formula, but Im not sure what the bases are since the trapezoid is shaped differently

dude:

Bases dont matter You're only trying to find the average between them

dude:

Or the order doesnt matter

Nicole:

we have to multiply the sum of the bases by the height and then divide by 2

Nicole:

so 11.75+12+13.42?

Nicole:

to find the sum of the bases?

dude:

No no youre not dividing everything by 2 \((\dfrac{b_1+b_2}{2})\cdot h\) Height is being multiplied separately

Nicole:

Oh okay but so we have to add 11.75+12+13.42 and then divide by 2?

dude:

That is a trapezoid

Nicole:

is the height6.12 or 18?

dude:

Height is 6.12 because it is the only vertical measure. You have 2 base lengths which happen to be parallel to each other. 11.75 and 18

Nicole:

so the answer is 91.035

dude:

Yep

Nicole:

http://prntscr.com/q5mhmu is this correct

dude:
