(a) 0.007 m² , it has only one significant figure. Because we know, Zeros to the left of the first non zero digit are not significant.
(b) 2.64 × 10²⁴ kg , it has three significant figure . Because we know, all the non-zero digits are significant figures.
(c) 0.0006032 m², it has four significant figure.
