प्रश्न
A rectangular sheet of paper is 12 `1/2` cm long and 10 `2/3` cm wide Find its perimeter.
उत्तर
Length = 12 `1/2` cm = `25/2` cm
Breadth = `10 2/3` cm = `32/3` cm
Perimeter = 2 × (Length + Breadth)
= `2 xx [25/2 + 32/3] = 2 xx [((25xx3)+ (32xx2))/6] = 2 xx [(75 + 64)/6]`
= `2 xx 139/6 = 139/3` = `46 1/3` cm
