Step-by-step solution for: Geometry Worksheets | Area Worksheets
To solve the problem, we need to identify each quadrilateral, calculate its area and perimeter, and determine its type. Let's go through each shape step by step.
- Type: Trapezoid
- Given:
- \( a1 = 8.7 \, \text{ft} \)
- \( a2 = 4.1 \, \text{ft} \)
- \( b1 = 5.86 \, \text{ft} \)
- \( b2 = 4.23 \, \text{ft} \)
- \( h = 4.2 \, \text{ft} \)
#### Area:
The formula for the area of a trapezoid is:
\[
\text{Area} = \frac{1}{2} \times (a1 + a2) \times h
\]
\[
\text{Area} = \frac{1}{2} \times (8.7 + 4.1) \times 4.2
\]
\[
\text{Area} = \frac{1}{2} \times 12.8 \times 4.2
\]
\[
\text{Area} = 6.4 \times 4.2 = 26.88 \, \text{ft}^2
\]
#### Perimeter:
The perimeter is the sum of all sides:
\[
\text{Perimeter} = a1 + a2 + b1 + b2
\]
\[
\text{Perimeter} = 8.7 + 4.1 + 5.86 + 4.23
\]
\[
\text{Perimeter} = 22.99 \, \text{ft}
\]
