The ratio of the perimeter of triangle PQR to the perimeter of rectangle ABCD is 5 : 9. All in centimeters

Triangle (sides) PQ: (x-3) PR: (3x-5) QR: (4x+3)
Rectangle (sides) AB: (2x+2) BC: (4x - 1/2) [AB is longer than BC]

a. Write algebraic expressions for the perimeters of triangle PQR and rectangle ABCD.

b. Write a linear equation using the algebraic expressions written in part a. Then solve for x.

c. Find the area of rectangle ABCD.

  1. [ (x-3) + (3x-5) + (4x+3) ] : [2(2x+2)+ 2(4x - 1/2) ] = 4 : 9
    (8x-5) / (12x+3) = 4/9
