Title: 6.1.2 Practice Explanation
Course: Illustrative Mathematics Grade 6 Unit 1 > Section: 6.1.2 Finding Area by Decomposing and Rearranging

I think it is possible to find the area.

Here's what I'd do:

I would add the extra spaces and subtract the white spaces from the area of 30 x 60

It is possible to find the area by calculating the area of extra spaces and adding it to the rectangle that is 50x30 or 1500 sq and then subtracting the white spaces.

We add 10x10 =100       subtract 5x10 =50 and 10 x 15 which is 150

so 1500 + 100 = 1600 - 50 = 1550 - 150 = 1400.

So the area is 1400 sq units.
