Answer:
i think the given triangle is equilateral triangle because all side are equal.
Round 1860 to 1900
1900x6=?
Break it down
60x1000=600
60x900=540
6000+5400=1400
That would be the estimate, but to get the actual answer it’d take a couple more steps.
Since we added 40 to get 1860 to 1900, and then multiplied it by 6, we’re going to multiply 40 by 6 and then subtract that to get the answer.
40x6=240
1400-240=1160
Hope this helped,
