1. The length of a rectangular field is 10 m morethan its breadth. The cost of fencing the field ata rate of 330 per metre is equal to 105 times thelength of the field. Find the length and breadth ofthe field.​

Answer»

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
