Question

A field is in the shape of a square of side 150m. the cost of fencing the field is 45 per meter. find the total cost of fencing the field.

Answer 1

Given:

Side of square field = 150 m

Perimeter = 4 × side

=》 4 × 150

=》 600 m

------

Cost of fencing = Rs. 45 per metre

=》 Cost for 600 m = 45 × 600

=》 Cost = $\textbf{Rs. 27000}$

Answer 2

Given - Side of square = 150 metre

Cost of fencing = 45 per meter

Find - Total cost of fencing

Solution - Fencing required for the square shaped field will be equal to the perimeter of square.

Perimeter of square is given by the formula = 4*side.

Keeping the value to find perimeter of field.

Perimeter = 4*150

Perimeter = 600 metre.

Now, fencing of one metre costs Rs. 45

So fencing of 600 metre will cost amount = 45*600

Amount of fencing of 600 metre = Rs. 27000.

Hence, total cost of fencing the field is Rs. 27000.
