Answer:
0.0015 km².
Step-by-step explanation:
It is given that a map is drawn to a scale of 1 cm to 250 cm.
It is given that an airport has an area of 240 cm² on the map. So, its actual area is
Therefore, the area of airport is 0.0015 km².
P = 2(L + W)
P = 228
L = 2W + 6
228 = 2(2W + 6 + W)
228 = 2(3W + 6)
228 = 6W + 12
228 - 12 = 6W
216 = 6W
216/6 = W
36 = W <=== width is 36 ft
L = 2W + 6
L = 2(36) + 6
L = 72 + 6
L = 78 <=== length is 78 ft
