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

Answer:

$(60\times 50)\div 3$

Step-by-step 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=$Length\times breadth$

Using the formula

Area of roll of sod=$3\times 1 feet^2$

Area of roll of sod=3 square feet

Area of courtyard=$60\times 50$ square feet

Number of rolls of sod needed=$\frac{Area\;of\;courtyard}{area\;of\;roll\;of\;sod}$

Using the formula

Number of rolls of sod needed=$\frac{60\times 50}{3}$

Number of rolls of sod needed=$(60\times 50)\div 3$

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