Lisa is preparing a bulletin board for the daycare center. She wants to divide the board into four sections by putting tape diagonally from corner to corner. The bulletin borad is 3 feet by 4 feet. How much tape will she need?

You have to square 3 and square 4 then add them then take the squareroot of that so

3^2=9

4^2=16

9+16=25

the square root of 25 is 5 so you need 5 foot for ONE corner to the next but you have to divide it into 4 part so it will be 5 times 2 so 10 foot
