Question

A field is in the shape of a rectangle whose length is 130 m and breadth is 95 m
respectively. Find the cost of fencing the field at * 20 per metre.
length and breadth are​

Answer 1

Answer:

length to be fenced is equal to perimeter of the rectangle and the perimeter of rectangle formula is 2 ×length + breath. so from here we can say that perimeter of the rectangle is 450

now cost of fencing is perimeter × 20 that is 450×20= 9000

therefore the cost of fencing is 9000 rs

Answer 2

Step-by-step explanation:

perimeter of rectangle = 2(l+b)

length = 130m

breadth = 95 m

perimeter = 2(130+95)

=2×225

450

cost of fencing = 20×450

=rupees 9000
