NEED THE HELP PLEAASE !!!The sides of ∆ABC are 30 units, 40 units, and 60 units long. The corresponding sides of ∆XYZ are r times as long as the sides of ∆ABCThe expression that gives the perimeter of ∆XYZ is ___130/r130r130rr65rIf the area of ∆ABC is n square units, the area of ∆XYZ is _ square unit nnrn(r r)n + r

Question

Answer:

The perimeter of triangle XYZ will be:

40r + 30r + 60r = 130r

The area of triangle ABC is n² so the area of triangle XYZ will be n²×r²
