What is the area of the shaded region?

First find the area of the square, which is 12m•12m=144m^2
Then the area of the circle: pi•3^2 = 28.27m^2

Then just subtract the area of the unshaded circle from the area of the square to find the area of shade.
144 — 28.27 = 115.73 m^2
Good luck!

The answer is 1 because you have to flip the sign when dividing by negative number and 3

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
