Question

The length of a rectangular playground is $3600cm$and the width is $2500cm$. Find the cost of levelling the ground at $₹3$ per square metre.

Answer 1

The length of a rectangular playground $=$$3600cm=36m$

The Breadth of a rectangular playground $=$$2500cm=25m$

So, the area of the playground $=length\times breadth$

$$\begin{gathered} =36\times 25 \\ =900 \end{gathered}$$

The area of the playground $=900m^2$

The rate of levelling of ground $₹3persquaremetre$

So, the total cost $=Rate\times Area$

$$\begin{gathered} =3\times 900 \\ =₹2700 \end{gathered}$$

Hence, the total cost of levelling of ground is $₹2700$.
