Answer:

3

Step-by-step explanation:

First, calculate the total area of the grass by calculating the area of the rectangle and the triangle, and then subtracting the triangle area from the rectangular area:

area of rectangle = width x length

⇒ area of rectangle = 7 x 12 = 84 m²

area of triangle = 1/2 x base x height

⇒ area of triangle = 1/2 x 6 x 3 = 9 m²

total area of the grass = area of the rectangle - area of triangle

⇒ total area of the grass = 84 - 9 = 75 m²

Given one box of fertilizer = 32 m² grass

⇒ boxes of fertilizer needed = area of grass ÷ 32

                                                = 75 ÷ 32

                                                = 2.34375

Therefore, Mrs Kunal will need 3 boxes of fertilizer.  

We need to round up to 3 rather than round down to 2, else she won't have enough to cover the entirey of the grassed area.

Answer:

3 boxes of fertilisers.

Solving steps:

<u>Part A</u>:

Area of the garden, rectangle:

Length * Width

12 * 7

84 m²

Area of patio:

\sf{\frac{1}{2}  * base *height

\sf{\frac{1}{2}  * 6*3

\sf{9 m²

Area of grass:

Area of the garden - Area of patio

84 m² - 9 m²

75 m²

<u>Part B</u>:

32 m² ↔  1 box

1 m²    ↔ \sf{ \frac{1}{32} box

75 m²  ↔ \sf{ \frac{1}{32} *75 boxes

75 m²  ↔ 2.34375 boxes

  • As she cannot buy exact 2.34375 boxes.

She should buy 3 boxes of fertilisers.

What are these fractions in simplest form?
Anton [14]
\frac{16y^{3}}{20y^{4}} =  \frac{4}{5y}
\frac{6xy}{16y} =  \frac{3x}{8}
\frac{abc}{10abc} =  \frac{1}{10}
\frac{mn^{2}}{pm^{5}n} =  \frac{n}{pm^{4}}
\frac{12h^{3}k}{16h^{2}k^{2}} =  \frac{3h}{4k}
\frac{8x}{10y} =  \frac{4x}{5y}
\frac{24n^{2}}{28n} =  \frac{6n}{7}
\frac{30hxy}{54kxy}  =  \frac{5h}{9k}
\frac{5jh}{15jh^{3}} =  \frac{1}{3h^{2}}
\frac{20s^{2}t^{3}}{16st^{5}} =  \frac{5s}{4t^{2}}
