Q. The Area of a field is 90 m2. If its breadth is 9 m, how much wire is required to fence the field?

Good Luck Friends!!! :-) :-) :-)

Answer 1

Answer:

Step-by-step explanation:

Let length =x metre area of the field = length ×breadth put the values 90=x × 9 therefore x=10metre now, wire required=2(length+breadth ) =2(10+9)metre =38metre HOPE IT HELPS YOU ...

Answer 2

given,
area of field=90m2
breath of field=9m
length of field=?

find,
length of fence required in field

sol.
area of field=2(l+b)

${90}^{2} = 2(9 + x)$
${90}^{2} = 18 + 2x \\ 8100 = 18 + 2x \\ 8100 - 18 = 2x \\ 8082 = 2x \\ 2x = 8082 \\ x = 8082 \div 2 \\ x = 4041$
therefore , length of field=4041m

length of fence=l×b

$4041 \times 9$
=36369
ans:legth of fence is 36369m.
