567 square mm
because 27*7 is 189 an times 3 because each side has 3 sides so it equals to 567 square mm! :)
C=10
Here’s how you solve it!
First multiply both sides by 2
Your equation will then look like this:
3c➕46=76
Then move your constant to the other side and when you do this you also have to change the sign
3c=76-46
Then subtract 76 and 46 which is 30
3c=30
Then you divide both sides by 3
c=10
Then you are left with your answer:
c=10
Hope this helps! :3
