Answer:

Step-by-step explanation:

how many packages does ellis need to buy to build the extension?

Ellis's backyard has a 6.25 m * 6.25 m patio

She would like to build a 1.5 m  wide extension around 3 sides of the patio,

Total Area = 3 * 6.25  * 1.5

She will buy 0.25 m * 0.25 m   text tiles that come 25  to a package.

Area of tiles in= 0.25 * 0.25 = 0.0625

Number of Tiles required =  3 *  6.25 * 1.5  / (0.0625)

= 450

Number of Packages required = 450/25

= 18
