Question

Find the area of a rectangular garden if length is 40m and breadth is

25m.Find its perimeter ?The garden is to be enclosed by three rounds

of fencing. Find the total wire required?​

Answer 1

Step-by-step explanation:

Length of the rectangular garden = 40 m

Area of the rectangular garden = 1000 sq. m.

∴ length × breadth = 1000

∴ 40 × breadth = 1000

∴ breadth = 1000/40 = 25 m

Now, perimeter of the rectangular garden = 2 × (length + breadth)

= 2 (40 + 25)

= 2 × 65 = 130 m

Length of one round of fence = circumference of garden – width of the entrance = 130 – 4 = 126 m

∴ Total length of fencing = length of one round of wire × number of rounds = 126 × 3 = 378 m

∴ Total cost of fencing = Total length of fencing × cost per metre of fencing = 378 × 250 = 94500

∴ The cost of fencing the garden is Rs 94500
