jim_thompson5910 · Answer

let b be the length of the base

|dw:1440553299702:dw|

jim_thompson5910 · Answer

area of parallelogram = base*height

so

A = b*h
24 = b*8 ... plug in A = 24 and h = 8. now solve for b

anonymous · Answer

So whats the perimeter

jim_thompson5910 · Answer

what is b equal to?

anonymous · Answer

Umm.... crud, I'm not sure

anonymous · Answer

wait, do I do 24*b8 to find b?

jim_thompson5910 · Answer

8 times something = 24

what is that something?

anonymous · Answer

I don't know... how do I find the something?

anonymous · Answer

I'm sorry, I'm just confused :(

jim_thompson5910 · Answer

try different numbers

8 times 1 = ??
8 times 2 = ??
8 times 3 = ??

etc etc

anonymous · Answer

OoOO 8*3=24

jim_thompson5910 · Answer

yes, so the base is 3

jim_thompson5910 · Answer

with ANY parallelogram, the opposite sides are congruent (ie equal)

jim_thompson5910 · Answer

to find the perimeter, add up all of the sides

jim_thompson5910 · Answer

the "8" is NOT one of the sides. So you don't add that to get the perimeter

anonymous · Answer

I added all of the sides up, and I got 30, is 30 correct?

jim_thompson5910 · Answer

30 is the perimeter, good
