-Wanderer- SG The figure below shows a rectangle WXYZ divided into 4 parts: A, B, C, D. The ratio of the area of A to that of area B is 1:3 and the ratio of the area B to that of C is 2:3. If WZ is 6 cm and area of D is 30 cm^2, what is the area of rectangle WXYZ?
-Wanderer- SG I can’t upload the diagram unless it is uploaded onto a URL. Anyone can help me with that? Thanks!
Ivifne SG you may upload your diagram in photobucket.com first then copy the link with [img]...[/img] here
Tangzhichen SG A : B = 1 : 3 = 2 : 6B : C = 2 : 3 = 6 : 9 D = C / B x A = 9 / 6 x 2 = 3A + B + C + D = 2 + 6 + 9 + 3 = 203 u -> 3020 u -> 20 / 3 x 30 = 200 cm2 The area of rectangle WXYZ is 200 cm2
