Question

The area of a room is 65 1/4 Sq metres .
If it's breadth is 5 1/16 metres .. What is its length

Answer 1

$length \: of \: a \: rectangle = \frac{area}{breadth} \\ = \frac{65 \frac{1}{4} }{5 \frac{1}{16} } \\ = \frac{ \frac{261}{4} }{ \frac{81}{16} } \\ = \frac{261}{4} \times \frac{16}{81} \\ = \frac{29 \times 4}{9} \\ = \frac{116}{9} cm \\ = 12.88888888......cm \\ = 13cm \: (approx)$

Answer 2

we know that length × breadth = area
let the length of room be x
5 1/16 × x = 65 1/4
81/16 × x 261/4
x = 261 ×16 /4×81
x = 29 × 4 /9
x = 12 8/9
