Answer 2

Appropriate Question:

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:

${\underline{\boxed{ \color{aqua}{\bf \: Area \: of \: field = Length×breadth}}}}$

Solution:

Area of field = length × breadth

Substitute the value in above formula we get

$\sf\dashrightarrow \: \: Area = 240×120$

$\sf\dashrightarrow \: \: Area = 28800 \: m {}^{2}$

Therefore, the area of the field is 28800m².

★ Now, Calculating the Cost Of mowing at a rate of Rs 10 Per m².

$\sf\dashrightarrow \: \: Total \: cost \: of \: mowing \: the \: field = Area \: of \: Field × Rate \: of \: Mowing .</p><p>$

$\sf\dashrightarrow \: \: Cost = 28800 ×10</p><p>$

$\sf\dashrightarrow \: \: Cost = Rs 288000</p><p>$

Therefore, Total cost of mowing the grass field is Rs 288000 .
