The total area of the field is 280 sq. ft.
"A process of finding the value of a single unit, and based on that value we can find the required value."
"[tex]A=l\times w[/tex], where l is the length and w is the width."
For given question,
We have been given the dimension of a plot which is 10 x 7 ft
From the dimension we can say that, a plot must be rectangular in shape.
Here, length (l) = 10 ft
and width = 7 ft
Using the formula for the area of the rectangle,
[tex]\Rightarrow A=l\times w\\\Rightarrow A=10\times 7\\\Rightarrow A=70~ft^2[/tex]
This means, the area of each plot is 70 sq. ft.
Four workers are hired to weed a field by hand.
Using unitary method the total area of the field would be,
[tex]70\times 4= 280~sq.ft.[/tex]
Therefore, the total area of the field is 280 sq. ft.
