Question

3.

You want to put siding on a house that is 18 meters long and 14 meters wide. The walls
are 4 meters high. There are two windows, each measuring 1.5 m by 2 m and a door
that is 1 m wide and 2.5 m high. The siding costs $12.50/m2. How much will it cost to
side the house? (10.3 Meeting) (10.5 Mastery)

Answer 1

Explanation:

Lets find the area of the siding

18*14*4, this is 1008

But there are 3 objects

there are two windows that are 1.5 by 2m

Each window has two 1.5 length sides and 2, 2m sides

adding those together is 3 by 4m

then adding these together is 7

The perimeter of the window is 7

then we do that again which would get us to the other window also having a perimeter of 7

adding those together we have a total perimeter of 14

Then we have a door that is 1x2.5

there is 2 2.5 and 2 1 so

1 + 1 is 2

2.5 + 2.5 is 5

thats 7 total

14 + 7 is 21

The total perimeter of those objects is 21

The total area of the siding that we needed before was 1008

From here honestly I dont know what to do because i dont know how area and perimeter work together like this

here u go
