Question

simple equation
Kapil wants to fence his rectangular kitchen garden @ Rs. 7 per
metre. If the length of a rectangle is twice its breadth and its perimeter
is 60 m, how much he needs to pay for fencing?

Answer 1

Answer:

rs.840

Step-by-step explanation:

length = 2x

breadth = 1x

2x+1x=60

3x=60

3x/3=60/3

x=20m

2x=40m

1x=20m

perimeter=2(l+b)

                =2(40+20)

                =2 x 60

                =120m

cost= 120 x 7

      = rs.840
