Question 912244
I'll do the first one to get you started


# 1 what will be the diagonal of a square whose perimeter is 60m?


Side Length = 60/4 = 15


a^2 + b^2 = c^2


15^2 + 15^2 = c^2


225 + 225 = c^2


c^2 = 2*225


c = sqrt(2*225)


c = sqrt(2)*sqrt(225)


c = sqrt(2)*15


c = 15*sqrt(2) <---- Exact length


c = 21.2132 <---- Approximate length
