jimthompson5910 (jim_thompson5910):
did you try breaking it up into rectangles and triangles?
OpenStudy (anonymous):
Yes, I was trying to break it up into triangles, and I've determined that there's four but I wasn't sure.
jimthompson5910 (jim_thompson5910):
here is one way

Alright, that helps a lot more.
OpenStudy (anonymous):
Do we have to find the area of all of them now?
jimthompson5910 (jim_thompson5910):
yes, then add up the individual areas
OpenStudy (anonymous):
Without numbers on the shape, how do I solve for the area?
jimthompson5910 (jim_thompson5910):
use the grid to figure out the base and height for each rectangle or triangle
each tick is 1 unit

for example, the largest rectangle in my drawing is 5x5 since there are 5 grid ticks along the width and height
OpenStudy (anonymous):
I still don't understand.
OpenStudy (anonymous):
Like I see what you mean, but i still don't know how to get the area.
jimthompson5910 (jim_thompson5910):
that rectangle would have an area of L*W = 5*5 = 25, agreed?
OpenStudy (anonymous):
Yes.

So the one next to it would be 9?
OpenStudy (anonymous):
Would the areas be 25, 9, 4, 4?
