Answer 2

Answer:

area of whole field =21×21

=441 m²

area of field except path = 15 ×15

=225 m²

area of path = 441- 225

= 216 m²

area of path is 216 m² .

Step-by-step explanation:

Work do one = 5/21

Remaining work = 1- (5/2) = 16/21

5/21 of a work can be done in 6 days working

10 hours a day by = 10 m

1 work can be done in 6 days working 10 hours a day by = (10 × 21)/5

1 work can be done in 1 day working 10 hours day by = (10 × 21 × 6)/5 men

16/21 work can be done in 8 days working 10 hours a day by = (10 × 21 × 6 × 16)/(5 × 21 × 8) = 24 men
