Find the cost of fencing a rectangular field 54 m long and 36 m wide with steel at the rate of Rs. 3 per metre

$\LARGE\sf{\texttt{{{Required Answer:}}}}$

Given ☆

• Length of the Rectangular Field = 54 m

• Breadth of the Rectangular Field = 36 m

• Rate of the steel per metre = Rs. 3

To Find ☆

• The cost of fencing the rectangular field

Formula Used ☆

• Perimeter of Rectangle = 2 × ( Length + Breadth )

Solution ☆

To find the cost of fencing the rectangular field, we need to first take out the perimeter of the field, and then multiply it with Rs. 3, so let's do it!

Perimeter of Rectangle = 2 × ( Length + Breadth )

Perimeter of Rectangle = 2 × ( 54 + 36 )

Perimeter of Rectangle = 2 × 90

Perimeter of Rectangle = 180 m

Now, let's find out the cost of fencing!

180 × 3 = ₹ 540

∴ The cost of fencing the Rectangular Field is ₹ 540

$\LARGE\sf{\texttt{{{Important Formulas:}}}}$

Perimeter of Square = 4 × side

Perimeter of Rectangle = 2 × ( Length + Breadth )

Perimeter of Triangle = Sum of all sides

Area of Square = side × side

Area of Rectangle = Length × Breadth

Volume of Cube = side × side × side

Volume of Cuboid = Length × Breadth × Height

Note : We can also write the formula Area of Square = side × side as Area of Square = ( side )² and Volume of Cube = side × side × side as Volume of Cube = ( side )³

Answer 2

Answer:

so, the area of the given rectangular field=

(54×36)sq.m

=1944sq.m

so,the cost of fencing=

(1944×3)rs

=5832rs

there is no formula to do this sum it is the simplest way to do these sum which is shown to you.
