Answer:
146 m²
Area of triangle:
- 1/2 * base * height
- 1/2 * 16 * 7
- 56 m²
Area of upper rectangle:
- Length * Width
- 8 * 9
- 72 m²
Area of bottom rectangle:
- Length * Width
- 6 * 3
- 18 m²
Total area:
- 18 m² + 72 m² + 56 m²
- 146 m²

Answer:
The length and width of the parking lot is 78 meters and 114 meters respectively.
Step-by-step explanation:
Given;
Perimeter of the parking lot =
Solution,
Let the width of the parking lot be x.
Then, according to question length = (x-36).
The perimeter of a rectangle is sum of all the sides of rectangle. Which is given by an expression;
Now substituting the values, we get;
Width =
Length =
Hence the length and width of the parking lot is 78 meters and 114 meters respectively.
The horizontal distance to the control tower is approximately 18506.83m
Data;
- distance from the ground = 3900m
- angle of elevation = 11.4 degrees
- horizontal distance = ?
To solve this problem, we need to use trigonometric ratio SOHCAHTOA.
In this case, we have the value of opposite and angle and we need to find the adjacent to the angle. The tangent of the angle would be perfect for this.
The horizontal distance to the control tower is approximately 18506.83m
