The ratio indicates that there are 8 dolls for every 7 teddy bears. That means that if there are 16 dolls, then there are 14 teddy bears. And that if there are 24 dolls, then there are 21 teddy bears. You could continue this pattern, or you could divide and multiply. If you have 160 dolls, then do 160/8 to simplify the ratio. You get 20. So if there are (8x20) dolls, then there is (7x20) teddy bears. 7x20 is 140, so there are 140 teddy bears.Comments Report

Answer:

128 ft sq.

Step-by-step explanation:

The way you find the area of a square is by multiplying one side by another, and since it is a square, the sides are the same. This means that if we have a square with a side length of x, the way to find the area of that square is to multiply x by x, which can be written as $x^2$ . Now, since we're doubling this, we can say that double Mary's garden is $2 * x^2$ . If we substitute 8 in for x, we have to multiply $8^2$ by 2 or 8 by 8 by 2 to find our answer. 8 times 8 is 64 and 64 times 2 is 128.
