Answer 1

What main idea of the question hear

Answer 2

Ellis needs to buy 21 packages of tiles to build the extension.

Explanation:

There are 3 rectangles that are 6.25 m by 1.5 and 2 squares with a side length of 1.5 m To build the extension, Ellis needs 32.625 m of tile. Each tile is 0.25 wide and 0.25 m long so Elis needs 16 tiles to build 1 m of the extension. Elis buys tiles in packages of 25. Since Ellis cannot buy part of a package, she will need 21 packages to have enough tiles. Ellis needs to buy 21 packages of tiles to build the extension. (*￣▽￣)b
