Area of the yard is 40 x 25 = 1000
how much area does the fertilizer cover?
Answer:
80 units
Step-by-step explanation:
The star has 10 sides. If each side is 8 units, then the perimeter is 10(80) because the perimeter is the sum of the lengths. With each length being 8, you could add 8 to itself 10 times, but it is faster to multiply.
6m=40hours
1m=40×6h
=240hours
4m=240÷4
=60 hours
divide 60 by 8
=7.5 days
thus,
4 men take 2 and 1/2 day more to complete the job.
