12. A blueprint for a picnic table has a scale of 1:20. The table in the blueprint is 3 in. long. What is the length of the actual picnic table?
O 5 feet
720 feet
60 feet
O 5 inches

The answer would be C :60 feet

Step-by-step explanation:

they already give you the ratio. 1:20 mean for every 1, 20 will be added. here is your scale-

1:20

2:40

4:80

5:100

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

x + 4/7
