We are given a
scale drawing of a rectangle with:
- Base (length) = 24 cm
- Height (width) = 14 cm
- Scale:
1 cm = 3 m
We need to find the
actual base and height of the figure in real life using the scale.
---
Step 1: Understand the scale
The scale tells us that
every 1 cm on the drawing represents 3 meters in real life.
So, to find the actual dimensions, we multiply each measurement on the drawing by 3.
---
Step 2: Calculate actual base
Drawing base = 24 cm
Actual base = 24 cm × 3 m/cm =
72 meters
---
Step 3: Calculate actual height
Drawing height = 14 cm
Actual height = 14 cm × 3 m/cm =
42 meters
---
✔ Final Answer:
-
Actual base = 72 meters
-
Actual height = 42 meters
These are the real-life dimensions of the rectangle represented by the scale drawing.
