if 2cm on a map represent 5km,what area is represented by an area of 9sq cm?
2*2 = 4 cm^2 represents 5*5 = 25 km^2
so, you have
9/4 * 25 = 56.25 km^2
Please add some explanation to this.
Please give some explanation on this question in doing direct proportion
wrong ans tha correct answer is 125 Km sq.
To determine the area represented by 9 square centimeters on the map, we need to find the corresponding real-world measurement.
Given that 2 centimeters on the map equal 5 kilometers, we can set up a proportion to solve for the real-world measurement:
2 cm on map / 5 km in reality = 9 cm² on map / x km² in reality
To solve for x, we cross-multiply and then divide:
(2 cm on map) * (x km² in reality) = (5 km in reality) * (9 cm² on map)
2x = 45
x = 45 / 2
x = 22.5 km²
Therefore, an area of 9 square centimeters on the map represents an area of 22.5 square kilometers in reality.
