The number of pack Jill needs is 7.
How to find the number of packs Jill needs?
The diagram shows the floor plan of Jill's dining room. Jill is going to cover the floor with wooden floorboards. The floorboards are sold in packs. One pack of floorboards will cover 2.25 m². Therefore, the number of packs Jill needs can be calculated as follows;
Therefore, let's find the area of the floor.
area of the floor = area of the first rectangle + area of the second rectangle
area of the first rectangle = 3 × 2
area of the first rectangle = 6 m²
area of the second rectangle = 4.5 × 2
area of the second rectangle = 9 m²
area of the floor = 15 m²
Therefore,
2.25 m² = 1 pack
15 m² = ?
cross multiply
number of pack = 15 / 2.25
number of pack = 6.66666666667
Therefore,
number of pack ≈ 7
