Answer:
52 meters.
Step-by-step explanation:
Let L represent the length of the actual piece of land.
We have been given that a blueprint of a plot of land has a scale of 1 1/4 cm to 3 1/4 m. The length of land measures 20 cm on the blueprint.
We will use proportion to solve our given problem.
Convert mixed fraction into improper fraction:
Cross multiply:
Therefore, the length of the actual piece of land is 52 meters.

Step-by-step explanation:
<u>Step 1: Define equation</u>
-9 = 2(18) + 9y
<u>Step 2: Solve for </u><em><u>y</u></em>
- Multiply: -9 = 36 + 9y
- Subtract 36 on both sides: -45 = 9y
- Divide both sides by 9: -5 = y
- Rewrite: y = -5
<u>Step 3: Check</u>
<em>Plug in y to verify it's a solution.</em>
- Substitute: -9 = 2(18) + 9(-5)
- Multiply: -9 = 36 - 45
- Subtract: -9 = -9
