Answer 2

Answer:

Let the length = 7x

Let the breadth = 4x

Perimeter of a rectangle = 2(l+b)

Cost of fencing per meter is rupees 25

And the actual cost is rupees = 3300

According to the question...

2(l+b) = 3300/25

2(7x + 4x) = 132

2(11x) = 132

X = 132/22

X = 6

Now, 7*6 = 42 unit

4*6 = 24 unit
