    perimeter is the total length of all the edges of the object so P=2*sqrt(75)+2*sqrt(48) P=2*sqrt(3*25)+2*sqrt(3*16) P=2*5sqrt(3)+2*4sqrt(3) P=10sqrt(3)+8sqrt(3) P=18sqrt(3)

    that's how to do it. but if you struggle with changing sqrt(75) ans sqrt48 into simpler form then I can get you more detail

    ok, so i think you have problem with that. sqrt = square root sqrt(75)=sqrt(3*5*5)=sqrt(3*5^2)=sqrt(3)*sqrt(5^2)=5*sqrt(3) 48 is similar

    rectangular has 2 longer edges and 2 shorter edges Perimeter = total lengths of 2 longer edges + total length of 2 shorter edges you know the longer edge is sqrt75 ft and shorter edge is sqrt48 ft, so parameter: P= sqrt75 + sqrt75 + sqrt48 +sqrt48 = 2sqrt75 + 2sqrt48

    so it would be 5 sqrt 3 plus 5 sqrt 3 plus 4 sqrt 3 or something

    5 sqrt 3 plus 5 sqrt 3 plus 4 sqrt 3 plus 4 sqrt 3 since 2 edges each.

    no problem, as long as you understand how it works, there shouldn't be any other problems

    what do you mean? the base should be a nice squared rectangle
