Answer»

Step-by-step explanation:

Using Proportionality Method,

725 m^2 ------------> 2.5

2001 m^2 ----------> X

725 : 2.5 :: 2001 : x

PRODUCT OF MEANS = PRODUCT OF EXTREMES

2.5 × 2001 = 725x

2.5 × 2001 / 725 = x

=> x = 6.9 L

ANSWER (I) 6.9 L

______________________________

(ii) USING PROPORTIONALITY METHOD,

725 : 2.5 :: x : 4.75

PRODUCT OF MEANS = PRODUCT OF EXTREMES

2.5x = 725 × 4.75

x = 725 × 4.75 / 2.5

=> x = 1377.5 m^2

ANSWER (ii) = 1377.5 m^2
