The table gives the surface areas, in square kilometres, of five seas.
zlopas [31]

The table is missing, so i have attached it.

Also, the correct question is;

The surface area of the East China Sea is k times the surface area of the Baltic Sea.

Work out the value of k.

Give your answer to the nearest whole number

Answer:

k = 3

Step-by-step explanation:

From the attached table,

Surface area of east china = 1.25 × 10^(6) km²

Surface area of Baltic sea = 4.22 × 10^(5) km² = 0.422 × 10^(6) km²

We are told that the surface area of East China Sea is k times that of the surface area of the Baltic Sea.

Thus;

1.25 × 10^(6) = k × 0.422 × 10^(6)

k = 1.25/0.422

k = 2.96

Approximating to whole number gives;

k = 3
