    Answer:

    Perimeter of NCAA court=288 feet

    Perimeter of new court=259.2 feet

    Step-by-step explanation:

    We are given that

    Length of NCAA court, l=94 feet

    Width of NCAA court, b=50 feet

    Width of new court, b’=45 feet

    We have to find the perimeter of an NCAA court and new court in the school.

    Perimeter of NCAA court=2(l+b)

    Perimeter of NCAA court=2(94+50)feet

    Perimeter of NCAA court=288 feet

    When two rectangles are similar then  the ration of their   corresponding sides are equal.

    Using the  property

    \frac{Perimeter\;of\;NCAA\;court}{Perimeter\;of\;new\;court}=\frac{Width\;of\;NCAA\;court}{Width\;of\;new\;court}

    \frac{288}{Perimeter\;of\;new\;court}=\frac{50}{45}

    Perimeter of new court=\frac{288\times 45}{50} feet

    Perimeter of new court=259.2 feet
