A. A baseball diamond is a square of 90 feet on each side. How long is a throw from first
base to third base?

B. The bottom of a 25 foot plank is placed approximately 7 feet from the side of a barn.
Approximately how far up the barn wall will the plank reach?

  • Algebra -

    a^2 + b^2 = c^2

    90^2 + 90^2 = c^2
    8,100 + 8,100 = c^2
    16,200 = c^2
    127.289 = c

    Do the same for the next problem.
