Answer 1

I am answering the first 4 question, post multiple questions to get the remaining answers

Q1) Apartment is 645 ft^2, since the units are ft^2. hence the given measurement denotes the area of the apartment

Hence the correct answer is Option A

Q2) 1 Km = 10^(9) um

Hence we need to multiply by 10^(9) to get the correct answer

Hence the correct answer is Option B

Q3)

Volume of the pool = 20m * 12m * 13 feet * 1m/3.28 feet

=> 951.21 m^3 = 951.21 * 10^(6) cm^3

Hence the correct answer is Option D

Q4)

Surface area of the field = 120 yards * 53.30 yards = 6396 yd^2

Hence the correct answer is Option C

6396/(1.09)^2 m^2 = 5383.30 m^2
