What will be the cost of mowing grass in a 3⁄4 of rectangular field of dimensions 240 m by 120 m at the rate ₹ 10 per sq. m as 1⁄4 of the land is covered with footpaths ?
Answers
Answer:
What will be the cost of mowing grass in a rectangular field 240 m long and 120 m wide at 10 per m²?
Given:
Length ( l ) = 240m
Breadth ( b ) = 120m
Rate of mowing = Rs 10 Per m²
To Find:
Cost of Mowing the Grass = ?
Formula used:
{\underline{\boxed{ \color{aqua}{\bf \: Area \: of \: field = Length×breadth}
Area of field = length × breadth
Substitute the value in above formula we get
\sf\dashrightarrow \: \: Area = 240×120⇢Area=240×120
\sf\dashrightarrow \: \: Area = 28800 \: m {}^{2}⇢Area=28800m
2
Therefore, the area of the field is 28800m².
★ Now, Calculating the Cost Of mowing at a rate of Rs 10 Per m².
\sf\dashrightarrow \: \: Total \: cost \: of \: mowing \: the \: field = Area \: of \: Field × Rate \: of \: Mowing . < /p > < p >
Answer:
Solution:
Area of field = length × breadth
Substitute the value in above formula we get
\sf\dashrightarrow \: \: Area = 240×120⇢Area=240×120
\sf\dashrightarrow \: \: Area = 28800 \: m {}^{2}⇢Area=28800m
2
Therefore, the area of the field is 28800m².
★ Now, Calculating the Cost Of mowing at a rate of Rs 10 Per m².
\sf\dashrightarrow \: \: Total \: cost \: of \: mowing \: the \: field = Area \: of \: Field × Rate \: of \: Mowing . < /p > < p >
