Question

what will be the cost of mowing grass in a rectangular field of dimension 240m by 120m at ₹10 per sq m

Answer 1

Area of the field = length * breadth
= 240 * 120
= 28800 sq.m

Now
Rate of mowing the grass = Re 10 / sq.m

Cost of mowing = Area * Cost
= 28800 * 10
= Re. 288000

Answer 2

area of the field= l×b= 240×120= 28800m²
cost of mowing grass per m. = Rs 10
cost of mowing 28800m² = Rs 10×28800m²
= Rs 288000
