Length:
Blue rectangle = 3 ft
Green rectangle = 6 ft
The ratio of the length of the blue and green rectangles is only the division of them:
ratio(blue to green length) = 3 ft / 6 ft = 1/2
Width:
Blue rectangle = 2 ft
Green rectangle = 4 ft
The ratio is:
ratio(blue to green width) = 2 ft / 4 ft = 1/2
Now, for the perimeter, we know that this is equal to the sum of all the sides of the rectangle.
Perimeter:
Blue rectangle = 2 ft + 2 ft + 3 ft + 3 ft = 10 ft
Green rectangle = 4 ft + 4 ft + 6 ft + 6 ft = 20 ft
The ratio is:
ratio(blue to green perimeter) = 10 ft / 20 ft = 1/2
Finally, for the area:
Area:
Blue rectangle = 2 ft * 3 ft = 6 ft²
Green rectangle = 4 ft * 6 ft = 24 ft²
The ratio is:
ratio(blue to green area) = 6 ft² / 24 ft² = 1/4
