Question

the area of a rectangular garden of length 40 m is 1000 square metre find the breadth of the garden and its parameter the garden is to be enclosed by three rounds of fencing living and entrance of 4 metre find the cost of fencing the garden at a rate of 250 rupees per metre ​

Answer 1

Answer:

Step-by-step explanation:

breadth = 1000/40= 25

fencing means perimeter

perimeter = 2(40+25)=2*65=130

cost per metre=250

cost = 130*250=32500

Answer 2

Given- l = 40m

          area = 1000m²

l x b = area

40 x b = 1000

        b = 1000

                40

        b = 25m

∴perimeter = 2(l + b)

                   = 2(40 + 25)

                   = 2(65)

                   = 130m

4 metres for entrence.

∴perimeter = 130 - 4 = 126m

The garden must be enclosed by 3 rounds of fencing.

∴fencing required = 126 x 3

                              = 378m

Rate of fencing = Rs.250/m

∴Cost of fencing = 378 x 250 = Rs. 94500
