Question

the length of a rectangular field is 580 metres and the breadth 470 find the area of the field in hectares and the cost of covering it with grass @ rupees 500 per are.​

Answer 1

Answer:

area = l x b

580x470

272600m²

27.26h

rupees for covering= 272600x500

136300000rs

Answer 2

Area of the field is 27.26 ha.

Cost of covering it with grass is Rs 1363000.

Step-by-step explanation:

Given:

Length of the rectangular field = 580 m

Breadth of the field = 470 m

Area of field = $length \times breadth = 580 \times 470 = 272600 m^2$

Now, $1 ha= 10000 m^2$

So, area of field = $\frac{272600}{1000} ha =27.26 ha$  ha

Cost of covering grass in 1 are or $100 m^2$ of area = Rs 500

Cost of covering grass in 272600 $m^2$ area = $\frac{500}{100} \times272600$ = Rs 1363000
