Answer:
Let w be the width of the rectangle. The length would be 2w+3. The area of the rectangle would be w(2w+3)=189.
So 2w2+3w-189=0 Solving for w you get w=9 or -10.5. Ignoring negative value Width of the rectangle would be 9mm and length of the rectangle would be 21mm giving you the area 189 square mm.
Hope this helps:)
It should be D, I did the math :)
East because it is the dimesndion of the quadrilateral
The dimensions would be: Length=36 and Width=32. I solved this by just using multiples of the numbers in the ratio. 9x4=36 and 8x4=32, so the ratio can still simplified to 9:8. P=2xL+2xW, so (2x36)+(2x32)=136.
L=36ft. and W=32ft.
