Question

Answer question 41 and 43

Answer 1

$lenght = 40 \tfrac{2}{3}m = \frac{122}{3} m \\ \: breadth = 25 \frac{1}{2} m = \frac{51}{2}m \\ perimeter \: of \: rectangular \: field = 2(length + breadth) \\ = 2( \frac{122}{3} + \frac{51}{2} )\\ = 2( \frac{244 + 153}{6} ) \\ 2( \frac{397}{6} ) \\ = \frac{397}{3} \\ = 132.33 \\ perimeter \: of \: rectangular \: field \: is \: 132.33m$
Heyy friend your answer is here

Answer 2

41. Length = 40 +2/3m
=122/3 m
Breadth = 25 + 1/2 m
=51/2 m
Perimeter = 2(122/3 + 51/2)
=2×244+153/6
397/3
=132 1/3m
