Question

Linda is cutting the grass on the school field. The field is a rectangle of 100 m long and 90 m wide. If you cut 30 m² of grass per minute how many minutes will it take me to cut it all?

Answer 1

300 minutes

Explanation:

area of the grass field=100 x 90 = 9000
`m^(2)`

[area of a rectangle = length x width ]

9000
`m^(2)`/30
`m^(2)` per minute=300 minutes
