Answer 2

$\times$Answer: 16,200

Step-by-step explanation:

First , let's find the area of the ground so that we can find the cost of levelling the ground.

Also, from the given measurements of the ground we understand that the ground is in the shape of a rectangle with length 45 m and width 30 m.

So , we can utilize the area formula of rectangle to find the area of the ground. Let's do that now,

i.e Area of ground = Length $\times$ width               ( this is formula to calculate  

                                                                            area of a rectangle )

                              = 45 m  30 m

                              = 1350 m²

Now, to find the cost of levelling the ground , we multiply the area with the rate of levelling the ground.

i.e Cost of levelling the ground = Area of the ground $\times$ Rate

                                                    = 1350 m² $\times$ 12 / m²

                                                    = 16,200

( Notice that the m² and / m² will get cancelled each other in the above cost calculation )
