Question

1. The length of a rectangular field is 10 m more
than its breadth. The cost of fencing the field at
a rate of 330 per metre is equal to 105 times the
length of the field. Find the length and breadth of
the field.​

Answer 1

Answer:

Let breadth =x m

length =x+10 m

perimeter =2(x+x+10)

=4(x+5) m

ATQ

4(x+5)×30=105(x+10)

120x+600=105x+1050

15x=450

x=30 m

breadth =30m

length =40 m
