Answer:
4,262.50 m
842 acres
Step-by-step explanation:
Given that :
Park is rectangular in shape
Width of park = 800 m
Area of park = 3.41 km²
Width of park = 800 / 1000 = 0.8 km
Area of rectangle, A
A = l * w
l = Length ; w = width
3.41 = l * 0.8
3.41 = 0.8l
l = 3.41 / 0.8
l = 4.2625 km
Hence, length in meters :
4.2625 * 1000
= 4,262.50 m
B.)
1 km² is approximately 247 acres
3.41km² = 3.41 * 247
3.41 km² = 842.27
= 842 acres
