Question

Area of a square field is 900meter square.Find the cost of boundry wall at the rate of Rs.50 per meter.

Answer 1

Step-by-step explanation:

to find perimeter of square if area is given:

4√900

4√100*9

4*10*3

40*3

120=perimeter

NOW,

120*50

6,000 rupees

Answer 2

EXPLANATION:-

Area of square field=900 m²

We know that we have to paint it on the sides boundary of wall ,SO we have to calculate the perimeter of the wall .

Perimeter of rectangle = 4×sides

And area of square=s²

Area of 900 m² [GIVEN]

So s²=900

s=√900

s=30

So the side of the square is 30 m

Now perimeter=4×side

=>30×4

==>120 m

So the perimeter of the rectangle =120

LET'S CALCULATE THE COST NOW:-

Cost=120×50

==>600

So the cost will be rs.600
