Questions: The sweptback triangular wings of an aircraft have the dimensions given in the figure shown to the right. Find the area of one wing in square feet. The area of one wing is approximately square feet.

Solution Steps

The problem provides the following dimensions for the triangular wing:

• One side (base) = 33.8 ft
• Height = 17.9 ft
• Angle between the base and height = 61°

The area \( A \) of a triangle can be calculated using the formula: \[ A = \frac{1}{2} \times \text{base} \times \text{height} \]

Substitute the given base and height into the formula: \[ A = \frac{1}{2} \times 33.8 \, \text{ft} \times 17.9 \, \text{ft} \]

Calculate the area: \[ A = \frac{1}{2} \times 33.8 \times 17.9 \] \[ A = \frac{1}{2} \times 604.02 \] \[ A = 302.01 \, \text{ft}^2 \]
