Question

The length and breadth of a rectangular field are 22cm and 144cm respectively. Find the cost of fencing to four sides at the rate of 8rupees per meter

Answer 1

Answer:

Step-by-step explanation:

First we have to find the perimeter. This is done because we have to find the cost of fencing the four sides only.

P = 2(L + B)

P = 2(22 + 144)

P = 2  *  166

P = 332 cm

Convert this into meter because it is cost per meter.

P = 3.32 meter

Rate = 8 rupees

Cost = rate * perimeter

Cost = 8 * 3.32

Cost = 26.56 rupees

Hope this helps:)
