Question

Pls answer.........​

Answer 1

Step-by-step explanation:

let the total surface be x

percentage of water on earth = 71%

=> percentage of land on earth = 29%

given

29% of x = 145.3 × 10⁶

=> 29/100 × x = 145.3 × 10⁶

=> x = 145.3 × 10⁸ / 29

=> x = 5.01 × 10⁸

=> x = 501 × 10⁶ sq.km

SO, TOTAL SURFACE AREA OF EARTH IS 501 MILLION SQ.KM
