Answer:

1. 30% 2. 160 square feet

Step-by-step explanation:

1.The entire area of the garden is 20x16=320 square feet

The area of the Zinnias(including roses) is 8x12 = 96 square feet

To get the percent, we have to divide the smaller number by the bigger number and multiply by 100, like 96/320x100=30%

2. The width progresses in the first rectangle by four 8 to 12, then again by four 12, 16 and again by four 16 to 20, which means that the next rectangle would have a width of 20+4=24. Doing the sale analysis for the height, we get that the increase is with 4 feet at a time or the new rectangle would have a width of 24 and height of 20, which means a total area of 480 feet. We would have to subtract all other rectangles and the new area would be 480 - (20x16) = 160 square feet

1. 30%

Conveniently enough, the roses and zinnias are right next to each other, within the same rectangle. 12 x 8 = 96 square feet.
But we need to know what percentage that area takes place within the whole garden, so we need the garden’s area too. 20 x 16 = 320 square feet.
Now, to find the percentage of roses and zinnias within the garden. We start by putting it as a fraction, 96/320, which simplifies to 3/10. You can now easily tell that 3/10, as a percentage, is 30%

2. 160 square feet

First, you have to analyze the blueprint and see what the pattern is for every new plant added. 4 is added to the length, and 4 is added to the width. 4 would be added from 20 and 4 would be added from 16 if alyssum was added, giving 24 x 20 = 480 square feet.
We now have to subtract the old area of the garden from the new one we just calculated. And we already calculated the old garden from the last problem!
480 - 320 = 160 square feet.
