Arectangular garden is extended 4% on the long sides and 8% on the short sides. to the nearest hundredth of a percent, by what percent does the area of the rectangle increase? (hint: let x = the length of the original long side and y = the length of the original short side. multiple the new side lengths and compare to x*y which is the area of the original rectangle.)

12.32%

Step-by-step explanation:

1. is the original long side and is the original short side.

2. The area of the original rectangle is .

3. The rectangle is extended 4% on the long sides and 8% on the short sides. therefore, the new long side is:

4. And the new short side is:

5. The new area is:

6. The percentage of increase is calculated by substracting the new area and the original area:

7. The result is:

(0.1232)(100)=12.32%
