Question

The area of a rectangle park is 600m2. If its length is 30m, determine its perimeter. Also, calculate the cost of fencing it @ruppes15/m.

Answer 1

let the x=breadth

x=600/30

x=20m

perimeter=2(l+b)

                =2(30+20)

                =2*50

                =100 m

cost of fencing =30*20=600 m2

                          = 600*15

                          =Rs9000

Answer 2

Area of rectangle= length × breadth

A/ Q

30 × b= 600

b= 600/30

b=20m

Perimeter of rectangle=2(l+b)

2(30+20)

=2×50

=100m

Cost of fencing at rupee 15/m

100× 15

= 1500 rupee Ans
