The total area of the field

= 8000 m^2.
So time taken to cut the whole field
= 8000/40
= 800/4
= 200 minutes.
It will take 200 minutes for Mo to cut the grass in the school field.
What is the area of a rectangle?
The area of a rectangle is the product of its length and breadth. Mathematically, it is given by l×b, where l is the length of the rectangle and b is the breadth of the rectangle.
To find the minutes will it take him to cut the grass at the rectangular field, firstly find the area of the rectangle.
100×80=8000 m²
Divide 8000 m² by 40 m²per minute.
8000 m²÷ 40 m²per minute=200 minutes
Thus, it will take 200 minutes for Mo to cut the grass in the school field.
