b. find the area of the pen.

1 Answer

  • we know that
    Applying the Pythagoras Theorem
    in a square
    c is the diagonal-----> 84 m
    c²=2a²--------> a²=c²/2-----> a²=84²/2-----> a²=3528-----------> a=√3528 m

    the answer part a) is
    √3528 m or 59.40 m

    the area of the pen is a²------> 3528 m²

    the answer Part b) is 
    3528 m²
