Answer:
1:9
Step-by-step explanation:
The area of the first rectangle = 20 square feet.
The area of the second rectangle = 180 square feet.
The ratio of their areas:
Area of rectangle 1: Area of Rectangle 2=20:180
Next, we reduce 20:180 to its lowest form.
20:180
Divide both sides by 10
This gives the ratio of the areas as:
1:9
