Answer 1

Answer:

Let length of graph be 24 cm

∴ Length of rectangle = 240 km        (Using scale 1 cm = 10 km)'

Let breadth of graph be 18 cm

∴ Length of rectangle = 180 km        (Using scale 1 cm = 10 km)

Area of land : area of water = 7 : 2

Let area of land = 7x

Let area of water = 2x

As total area = 240 × 180 = 9x

∴ x = 4800

∴ Area of land = 7x = 33600
