Answer:
Step-by-step explanation:
Area = l x w
180 = 15 x w
180/15 = w
1.w = 12 meters
wallpaper
2. 2 (15x3) + 2(12x3) = 162 square meters
one meter border 12 + 12 + 15 + 15 = 54
3. take this away from the area 180 - 54 = 126
4. kitchen perimeter = 5 + 13 + 12 = 30
5. area of triangle = 1/2 b h = 1/2(5 x 12) = 30 square meters of tile
assume ceilings are 3 m tall as in the living room
(5x3) + (12x3) + (13x3) = w - walls to be covered
15 + 35 + 39 = 90 divide by 5 square meters per can of paint
6. 18 cans of paint
7. 18 x 16 = 288 square meters
