Answer 1

Answer:

21

Step-by-step explanation:

Area to be covered:

(6.25 + 1.5)(6.25 + 2(1.5)) - 6.25²

= 32.625

Each title's area = 0.25² = 0.0625

No. of tiles needed:

32.625 ÷ 0.0625

= 522

25 in each pack

522/25 = 20.88

So 21 packets

Answer 2

First, let's find the area of the patio:

6.25 * 6.25 = 39.0625

Next, we need to find the area of the patio and extension combined:

We know that the patio is now 3m wider and 1.5m longer.

(6.25 + 3) * (6.25 + 1.5)

9.25 * 7.75 = 71.6825

Then, we need to find the area of the extension alone, which can be done by subtracting the area of the patio from the area of the patio and extension combined:

71.6825 - 39.0625 = 32.625

Now, find the area of one tile:

0.25 * 0.25 = 0.0625

And divide the area of the extension by the area of one tile to find the number of tiles needed to build the extension:

32.625 / 0.0625 = 522

Divide the total number of tiles by 25 and round up to the nearest whole number to find the number of packages:

522 / 25 = 20.88

20.88 rounds up to 21 packages of tiles.

Ellis needs 21 packages of tiles.

Hope this helps!! :)
