Question

The longer side of a rectangular hall is 24 m and the length of its diagonals is 26 m. Find the area of the hall.

Answer 1

24X26
is the correct answer

Answer 2

length of the rectangular hall = 24m
diagonal of the rectangular hall = 26m
base = ?


${(length)}^{2} + {(base)}^{2} = {(diagonal)}^{2}$
$576 + {(base)}^{2} = 676$
${(base)}^{2} = 100$
$base = 10$
now the area of the rectangular hall = l x b

$= 24m \times 10m = 240 {m}^{2}$
