Question

7 Jon is using square ceramic tiles, each 20cm x 20cm, to cover a rectangular worktop in his greenhouse. He can fit exactly 6 tiles along the shorter edge of the worktop and 15 along the length. (a) How many tiles will he use, altogether, to cover the orktop? (b) What is the length of the worktop? Give your answer in metres (m). ............m​

Answer 1

(a) The number of tiles Jon will use to cover the worktop is 6 * 15 = 90 tiles.

(b) To find the length of the worktop, we first need to find the length of each tile, which is 20 cm = 0.2 m.

The length of the worktop is then 0.2 m * 6 tiles = 1.2 m.

The width of the worktop is 0.2 m * 15 tiles = 3 m.

So, the length of the worktop is 1.2 m and the width is 3 m.
