Question

the cost of watering a square field at the rate of rs 8 per square is 8192 rs find the length of the field?

Answer 1

Cost of watering a Square field= 8192Rs

cost of watering Per Square metre = 8Rs

Then the no.of Square metres in that field

=Cost of watering a Square field/cost of watering Per Square metre

=8192Rs/8Rs = 1024sq metres= Area

we know that Area of a Square = Side^2

side^2 = 1024

side = √1024 = 32

length of a side = 32 metres, Area of the sqaure field = 1024square metres

Answer 2

Cost of watering a Square field= 8192

cost of per Square metre = 8

Area of the field

= Total Cost/cost per metre

=8192/8

=1024m^2

Area of a Square = length of the Side^2 = 1024

length of the side = √1024 = 32m
