The perimeter of the rectangle field -198018-110-xA0-mThe width of the field -23-xA0-mWe know that2-length-width-110Therefore-2-length-23-110length-23-55length-32-xA0-mHence- this is the answer-

The cost of fencing a rectangular field at $R s 18$ per metre is $R s 1980$ . If the width of the field is $23 m$ find its length.

The perimeter of the rectangle field $= \frac{1980}{18} = 110 m$

The width of the field $= 23 m$

We know that
$2 (l e n g t h + w i d t h) = 110$

Therefore,
$2 (l e n g t h + 23) = 110$

$l e n g t h + 23 = 55$

$l e n g t h = 32 m$

Hence, this is the answer.

The cost of fencing a rectangular field at Rs18 per metre is Rs1980. If the width of the field is 23m find its length.

The perimeter of the rectangle field =198018=110 mThe width of the field =23 mWe know that2(length+width)=110Therefore,2(length+23)=110length+23=55length=32 mHence, this is the answer.
