Question

the length and breadth of a rectangular field are 400 m and 250 m. find its area. also, find the number of plants which can be planted in this field of one plant requires 12.5m x 12.5 m field ?
​

Answer 1

$\sf Answer$

Length of a rectangular field = 400 m

Breadth of a rectangular field = 250 m

Area of rectangular field = Length × Breadth

Area of rectangular field = (400 × 250) m²

Area of rectangular field = 1,00,000 m²

If one plant requires area upto 156.25 m²

1 m² = 1/156.25 plants

100000 m² = 100000/156.25 plants = 640 plants

640 plants is the required answer
