Question

5. The breadth of a rectangular field is twice its length. If the area of the field is 1058 m^2 , find the cost of fencing it at ₹35 per m.​

Answer 1

Step-by-step explanation:

Length =x

Then, breadth =2x

Area=1058m^2

lb=1058m^2

x×2x=1058

2x^2=1058

x^2=1058/2

x^2=529

x=root of 529

x=23

There fore

Cost of fencing =23×35

• 805

Answer 2

Answer:

l=2x

h=x

area =l×b

1058m^2=2x × x

1058m^2=3x

x=3/1058

x=352.6

cost of fencing =352.6×35

=₹12341
