a farmers vegetable plot is 27m long and 16m wide how much would her pay to plough it at $50.75 metres quare

The cost of 432 meters square = $21924

Step-by-step explanation:

The length of the plot = l = 27m

The width of the plot = w = 16m

We know that the area of a rectangular object can be determined by multiplying the length and width.

Thus, the area of the rectangular vegetable plot will be:

substituting w = 16 and l = 27

A = 16 × 27

A = 432 m²

Therefore, the vegetable plot will be:

A = 432 meter square

Given

The cost of ploughing field of 1 meter square =  $50.75

so

The cost of ploughing field 432 meters square = 50.75 × 432

                                                                               = $21924

Therefore, the cost of 432 meters square = $21924
