3. The length of a football ground is 100 m and width 40 m. Find the perimeter of the ground. Also find the cost of fencing it with wire at the rate of 2.50 per metre.

Cost of fencing it with wire is at the rate of ₹2.50 per metre.

Tofind:

Solution:

As the dimensions of the football ground are different (100mand40m), hence the ground is in rectangular shape. Therefore we’ll apply the formula for rectangleonly.

We have to fence the ground, therefore we’ll find the perimeter.

Answer:4000m=perimeter

fencing=2.5*4000=10000

fencethe ground, therefore we’ll find theperimeter.[tex] \: [/tex][tex]\boxed {\mathfrak {\red {Perimeter\ of\ rectangle = 2(length\ +\ breadth)}}}[/tex]

Perimeter of ground = 2 (100+40)

Perimeter of ground = 2×140

Perimeterofground=280m[tex] \: [/tex]

Cost of fencing 1 m of ground = ₹2.50

Cost of fencing the entire ground = ₹ (280×2.50)

= ₹ 700
