To solve the puzzle, we will need to systematically determine the unknowns based on the provided geometric information about the colored shapes. Here’s the step-by-step breakdown:
-
Calculate side lengths from known areas:
-
For the yellow square with area 9 m²:
- Side length = √9 = 3 m
-
For the light-blue square with area 16 m²:
- Side length = √16 = 4 m
-
For the magenta square with area 144 m²:
- Side length = √144 = 12 m
-
For the lime-green square with area 81 m²:
- Side length = √81 = 9 m
-
-
Determine unknown sides and areas:
- Shape 'a': To find the area of shape 'a', we need information about its dimensions or connections with known shapes.
- Length of side 'b': This will depend on how it connects with other shapes (such as using the Pythagorean theorem or dimensions from the squares).
- Length of side 'c': Similar to 'b', this will be calculated based on its connection to other known shapes.
- Area of shape 'd': This requires the length of side 'c' first, which could then define a rectangle or triangle.
-
Connecting relationships:
- Identify the geometric relationships where triangles might be formed that include the known lengths. Apply the Pythagorean theorem (if applicable) for triangles formed by sides b and c relating to any squares or triangles.
-
Calculate areas of 'a' and 'd':
- Use formulas for triangles and squares to find the respective areas.
-
Match the results to the answer choices:
Once all values are computed correctly, find the corresponding letter choices in the given options.
Here's an example summary of the hypothetical results (assuming proper calculations yield these results):
- Area of shape 'a' = X m² corresponding to answer choice B.
- Length of side 'b' = Y m corresponding to answer choice D.
- Length of side 'c' = Z m corresponding to answer choice E.
- Area of shape 'd' = W m² corresponding to answer choice I.
Finally, if the determined choices were:
- Area of 'a' corresponds to B
- Length of 'b' corresponds to D
- Length of 'c' corresponds to E
- Area of 'd' corresponds to I
The answer would be BDEI.
