Answer 1

Perimeter of the rectangle field=2(l+b)=2(35+28)=2*63=126m
Total length to be fenced=123m
Therefore, cost required=Rs. 1230

Answer 2

Step-by-step explanation:

Given :-

• Length of field = 35 m
• Breadth of field = 28 m
• Width of gate = 3 m
• Rate = ₹ 10 per m

To Find :-

Total cost

Solution :-

We know that

$\pmb{ \bf Perimeter\:= 2(l +b)}$

=> Perimeter = 2(35 + 28)

=> Perimeter = 2(63)

=> Perimeter = 126 m

Now,

Since 3 m width is of gate in which fencing is not necessary. So,

Total length of fencing = 126 - 3 = 123 m

Now,

=> Cost = Rate × Perimeter

=> Cost = 10 × 123

=> Cost = ₹1230
