Question

a rectangle brass sheet of length 1.5 m and breadth 75 cm weighs 7.2 kg.Find area
in m2 of another similar sheet of brass which weighs 12.8 kg​

Answer 1

Step-by-step explanation:

area =l*b

=150*75=11250

then,

if area is 11250cm^2 then weight is 7.2kg

then if weight is 12.8 kg

area of brass =11250/7.2=1562.5

=1562.5*12.8=20000cm^2

answer is 20000 cm^2
