Consider Theorem 8.1, Perimeters of Similar Polygons.
Perimeter of NCAA Court: 288feet
Perimeter of School Court: 259.2feet
We are given two similar basketball courts, which can be modeled in the following diagram.
We want to find the perimeter of both courts. Let's start with the perimeter of the NCAA basketball court.
l_N= 94, w_N= 50
Multiply
Add terms
To find the perimeter of the school court we will recall Theorem 8.1.
Theorem 8.1: Perimeters of Similar Polygons |
If two polygons are similar, then the ratio of their perimeters is equal to the ratios of their corresponding side lengths. |
Substitute values
LHS * 288=RHS* 288
Calculate quotient
