I have a chapter test tomorrow, and we got a review sheet that is said to basically be the same as our chapter test tomorrow. Well, I got everything else on the review sheet, except this one question:
A rectangle has a length of 5 cm and a width of 4 cm. Every dimension is tripled to form a second rectangle. What is the ratio of the areas of the two rectangles? |
