Question
If A denotes area of a rectangle, l represents its length and b represents its breadth, find:
l, if A = 48 cm² and b = 6 cm
l, if A = 48 cm² and b = 6 cm
✓
Answer
l, if A = 48 cm² and b = 6 cm
$I =\frac{ A }{ b } \quad\left[\because A = l \times b \Rightarrow l =\frac{ A }{ b }\right]$
$\Rightarrow l =\frac{48 cm ^2}{6 cm }=8 cm$
$I =\frac{ A }{ b } \quad\left[\because A = l \times b \Rightarrow l =\frac{ A }{ b }\right]$
$\Rightarrow l =\frac{48 cm ^2}{6 cm }=8 cm$
