Answer 1

Answer:

₹ 600000

Step-by-step explanation:

We need to find out the area of rectangular field,

Area = Length * Breadth

= 600m*400m

= 240000m square

Cost of planting grass in 1 metre square= ₹ 2.50

Required money= 2.50×240000

= ₹ 600000

Answer 2

To find : to find cost of grass to be planted in rectangular field.

Given : length $= 600\ m$ and breadth $= 400\ m$

Solution :

• According to question we are given that length and breadth  rectangular field is $600\ m$ and $400\ m$ respectively. To find cost of grass to be planted in rectangular field. We find area of field .  

• To find area we use following formula -

        Area of rectangular field =  $l \times b$

        Substituting the values we get,

• Area of field  $= 600\ m \times 400 \ m$

                               $= 240000 m^{2}$

• Now,

      $Cost\ of \ grass \ to \ be\ planted = area \ of \ field \ \times rate\ per \ m^{2}$  

                                                   $= 240000\ m^{2} \times 2.50 Rs v\\= 600000Rs$

Hence, cost of grass to be planted in rectangular field is $600, 000Rs$.
