Solution
Let's go over each polygon one by one and calculate the area according to the given information.
First Image
1. Trapezoid
- Base 1: 17 yd
- Base 2: 6 yd
- Height: 16.1 yd
- Formula: where and are the lengths of the parallel sides and is the height.
2. Triangle
- Base: 35 in
- Height: 17.1 in
- Formula: where is the base and is the height.
3. Trapezoid
- Base 1: 12 yd
- Base 2: 6 yd
- Height: 8.8 yd
- Formula:

I will now calculate the areas based on these formulas and dimensions. Let me perform the calculations.Here are the areas of each polygon from both images:
First Image:
- Trapezoid: 185.15 square yards
- Triangle: 299.25 square inches
- Trapezoid: 79.20 square yards
- Rectangle: 1920 square feet
- Square: 100 square inches
- Rhombus: 80 square yards
Second Image:
- Rhombus: 132 square inches
- Rhombus: 1417.5 square centimeters
- Trapezoid: 1104 square inches
- Right Triangle: 8 square inches
- Triangle: 264 square centimeters
- Trapezoid: 24 square feet
Let me know if you'd like any further clarification or detailed explanations!
Would you like to know more details about any of the calculations? Here are 5 follow-up questions to expand your understanding:
- How do you calculate the area of a trapezoid with uneven base lengths?
- Why is the formula for a rhombus based on its diagonals rather than its sides?
- What would be the area if the measurements were converted to different units?
- How can we derive the formula for the area of a triangle?
- What are other common ways to find the area of irregular polygons?
Tip: Always ensure that units of measure are consistent when calculating areas. Converting to the same units before calculating helps avoid mistakes.
