To graph use your graphing calculator and plug in the function to y = and graph it
Part a) Find the expression that gives the perimeter of ∆XYZ
we know that
Perimeter of triangle ABC is equal to

In this problem ∆ABC and ∆XYZ are similar triangles
the scale factor is equal to r
so

therefore
the answer Part a) is
The expression that gives the perimeter of ∆XYZ is 
Part b) Find the expression that gives the area of ∆XYZ
we know that


therefore
the answer Part b) is
The expression that gives the Area of ∆XYZ is 
Answer:28.5
Step-by-step explanation:
