Question

Find the area of the parallelogram.

A) 640 in^2
B) 512 in^2
C) 384 in^2
D) 240 in^2

This problem is confusing. How would I go about finding the height? It's not 12, right?

Answer 1

There is no picture...

Answer 2

Sorry, had to find it.

Answer 3

first you know how its
1/2 * (a+b) * h
then a is 32
b is 32+12
h is found using pythagorean theorem
square root of 20^2 - 12^2
so using formula you have
0.5*(32+12)*32*stuff = 608 inches ^2
ok... so thats not one of the choices.. either im wrong or the choices, will try again and write again... coming soon.

Answer 4

Isn't it base times height?

Answer 5

OH I HAVE IT!
the area of the trapezium is 608 now subtract area of the triangle which gives
608 - 20*12 /2 = 608 - length done in previous question gives 5*12 which is BBBBBBB

Answer 6

OH I see how to use the pythagorean theorem now
