Heya! In the given figure, PQRS is a square. A , B , C and D are the points on the sides PQ , QR , RS and SP respectively. If AQ = BR = CS = DP , prove that ABCD is also a square.

​

B.-2,3 because it is touch the -3 i think that the answer

Planet earth has a mass of 5.9726x10²⁴ kg.then: 5.9726x10²⁴ kg=100% of the total earth mass.if the water´s mass=5x10-4 % of the total mass, we can solve this problem by the rule of three.5.9726x10²⁴ %*10⁻⁴ %x=(5.9726x10²³ kg)(5*10⁻⁴  %) / 100 %=2.9863x10¹⁹ kganswer:   the mass of the planet´s water would be   2.9863 x 10¹⁹ kg.
