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

OpenStudy (anonymous):

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

jimthompson5910 (jim_thompson5910):

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.

OpenStudy (anonymous):

So the one next to it would be 9?

OpenStudy (anonymous):

Would the areas be 25, 9, 4, 4?
