Question

4
The cost of fencing a rectangular garden at Rs. 5.50 per m is Rs.
3300. If its length is 180 m, find its breadth.​

Answer 1

Answer:

Let the length of the rectangular garden be 4x.

Then breadth=3x.

Area of rectangle=length×breadth

So, area of the rectangular garden=12x2

Area(given)=1200

⇒12x2=1200

⇒x=10

Hence, length=4x=40m

Breadth=3x=30m

Perimeter=2(l+b)=2(40+30)=2×70=140m

Cost of fencing 1m=Rs.7.50

So, cost of fencing 140m=140×7.50=Rs.1050

Answer 2

answer the breadth of the rectangular Garden is 120

Step-by-step explanation:

for solving it we have to divide the total cost of fencing the rectangular garden with the cost per metre and then after dividing these two we get the perimeter of rectangular garden so from this we can find out breadth

3300÷5.50=600

600 is our perimeter of the rectangular Garden

then formula of rectangular perimeter is equals to 2 into length + breadth

so 600=2×(180+b)

600÷2 = 180+b

300= 180+b

300-180=120 and so that's why 120 is our breadth of the rectangular Garden
