Question

10. The length and breadth of a rectangular field
are in the ratio 7: 4. The cost of fencing the field at rupees25
metre is rupees 3300. Find the dimensions of the field.

​

Answer 1

Answer:

Let the length be 7x and breadth be 4x

2(7x+4x)25 = 3300

50 × 11x = 3300

11x = 3300÷50

11x = 66

x = 66÷11

x = 6

So length is 7×6=42cm and breadth is 4×6=24 cm
