Question

A restaurant owner is planning to have a courtyard area sodded. The sod comes in rolls that are 3 feet long by 1 foot wide. If the courtyard measures 60 feet by 50 feet, which of the following expressions represents the number of rolls of sod needed?

Answer 1

`(60* 50)/ 3`

Explanation:

We are given that

Length of roll of sod, l=3 feet

Width of roll of sod, b=1 feet

Length of courtyard, L=60 feet

Breadth of courtyard, B=50 feet

Area of rectangle=
`Length* breadth`

Using the formula

Area of roll of sod=
`3* 1 feet^2`

Area of roll of sod=3 square feet

Area of courtyard=
`60* 50` square feet

Number of rolls of sod needed=
`(Area\;of\;courtyard)/(area\;of\;roll\;of\;sod)`

Using the formula

Number of rolls of sod needed=
`(60* 50)/(3)`

Number of rolls of sod needed=
`(60* 50)/ 3`

This is required expression which represents the number of rolls of sod needed.
