Write to explain how you can break apart 16 x 34 into four simpler multiplication problems

Think of the tens and the units separately:

16 x 34

= (10 + 6)(30 + 4)

Then we can distribute and get:

10(30 + 4) + 6(30 + 4)

And then further to get:

(10 x 30) + (10 x 4) + (6 x 30) + (6 x 4)

Each of these multiplications is easy enough to do in your head:

300 + 40 + 180 + 24

Add up the results:

300

180

I'm confused. Wow. I didn't know this could happen with a simple looking formula.

Area=120 cm

Step-by-step explanation:

I think for each separate figure you find the area and then add them up to find the total area. The formula to find the area here is length times width or base times height.

First figure: 12 times 5= 60 cm

Second figure=8 times 5=40cm

Together we have 100cm as our area, that might be wrong, look in the comments, thanks for correcting me :)
