Question

The length and breadth of a rectangle is twice its breadth. If it's breadth is 20m , find the cost of levelling it a rate of of rs. 3.50 per meter

Answer 1

Given :

• The length and breadth of a rectangle is twice its breadth.

• Its breadth is 20m.

To find :

• The cost of levelling it a rate of of rs. 3.50 per m =?

Step-by-step explanation :

The length and breadth of a rectangle is twice its breadth. [Given]

So, Lenght = 2(20) = 40 m.

As We know that :

Area of the rectangle = length x breadth

Substituting the values in the above formula, we get,

= 40 × 20

= 800.

Therefore, Area of rectangle = 800m².

Now,

The cost of levelling = 3.50 × area of rectangle

Substituting the value, we get,

= 3.50 × 800

= 2800.00

Therefore, Cost of levelling = ₹ 2800
