The area is the length times the width. Find area of shapes by counting unit squares. Some shapes will require combining partial square units to find area.<span>
For example - </span><span>A rectangle is 5 centimeters long and 4 centimeters wide. What is its area? </span>
Area = Length * width
The length is <span><span>5</span></span> centimeters. The width is <span><span>4</span></span> centimeters. So the area is <span><span>5 times </span>4</span> square centimeters.

Answer:
D. 158.4 km²
Step-by-step explanation:
Area of sector = θ/360 * πr²
Where,
θ = 150°
r = 11 km
Substitute
Area = 150/360 * π * 11²
Area = 158.38863 ≈ 158.4 km² (nearest tenth)
