How many acres are in the field in figure 5-2? the land sold for $5,259 per acre. what did the land cost?

34.425 acres

$181,041.08

Step-by-step explanation:

1. Draw a dotted line at the endpoint of the 3 units side connecting to the line on the opposite side. Make sure this line is parallel to your 8.1 unit side.

2. This gives you a rectangle and a triangle. You can determine the area of the rectangle by multiplying the sides ( 8.1 times 3). Doing this will yield an area of 24.3 acres for the rectangle.

3. The area of the triangle can be determined by using the 1/2 base times height formula. The base will be the difference between the two short sides (5.5 - 3), which is 2.5. Using the height of 8.1 and inserting these numbers into the formula, the trianglular area is 10.125 acres.

4. Add the two areas together, which will come out to 34.425 acres.

5. Multiply 34.425 acres by the price of an individual acre ($5259) to get the final answer!

C,B,A

Step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)
