Answer:
60%
Step-by-step explanation:
The total area is 136ft^2
We know this because the length of Hal's Backyard is 8+9 ft. This is a total of 17 ft in length. The width is 5+3 ft. This is a total of 8ft. Multiplying the length by the width gets us: 17ft*8ft = 136ft^2.
Now we need to find the ft^2 taken up by the padio, walkway, and garden. - We can see the image the patio is 5ft by 8ft. This is a total of 40ft^2.
- We can see the image of the garden is 3ft by 6ft. This is a total of 18ft^2
- We can see the image of the walkway is 3ft by 8ft. This is a total of 24ft^2
This adds up to a total of 82ft^2: 40ft^2+18ft^2+24ft^2 = 82ft^2
Now, to find the percentage, we divide the area of the patio, walkway, and garden by the total area:
[tex]\frac{82ft^2}{136ft^2}[/tex]
=
60%
So Hal's patio, walkway, and garden make up 60% of the total area of his backyard.
Hope this helps! :3
