Given that DRWH is a parallelogram, determine the values of x and y.

Question

side length DR= 2y + 2

side length RW= y + 4

side length HW= 3y - 9

side length HD= 3x +6

Answer 1

DB=HW so 2y+2 = 3y-9; this means y = 11

BW=HD so 3x+6 = y+4; this gives 3x+6 = 11+4, so 3x = 9; thus x = 3.

 

(x,y) = (3,11).
