Betty went to the hardware store and bought 2 identical wooden boards. When Betty placed the boards end-to-end, the line was 7 meters long. How long was each board?

Answer 1

Two equal boards together are 7 m long, so each individual board is 7/2 = 3.5 m long.

Answer 2

x = the size of the boards

Size of board 1 + Size of board 2 = Total Size

x+x = 7

2x=7 Divide both sides by 2

x=3.5

Each board is 3.5 m long
